Now we always expect type names inside of *ast.FieldList. This expands
the previous func signature logic to also work for *ast.StructType
and *ast.InterfaceType. For example, we will now prefer type names in
cases like:
type myStruct struct { i i<> }
Also, fix a check for anonymous fields to make sure the field is
actually embedded. This fixes cases like this to properly have no
completions:
type myStruct struct { i<> i }
where this will still give type name completions:
type myStruct struct { i<> }
I introduced a new error type source.ErrIsDefinition so source_test.go
could avoid erroring out on tests that make sure definition

Normally you don't want literal candidates for basic types (e.g.
"int(0)") since you can type the literal value without the type name.
One exception is if you are creating a named basic type that
implements an interface. For example:
http.Handle("/", http.FileServer(<>))
will now give "http.Dir()" as a candidate since http.Dir is a named
string type that implements the required interface http.FileSystem.

In it previous implementation, tool.Main was meant to be called from
an applications main(). If it encountered an error it would print the
error to standard error and exit with a non-zero status (2).
It is also called recursively and in various test functions.
Exiting on an error makes testing difficult, unnecessarily.
This change breaks the functionality into to parts: an outer
tool.MustMain() that is intended to be called by main() functions and
an inner Main that is used by MustMain() and by test functions.
None of the existing test functions use Main()'s error value, but the
failure case tests for the command line invocation of rename (#194878)
require it.

We were recursing infinitely in cases like this:
switch true {
case true:

}
There were three things that came together to cause this:
1. We recently starting recursively fixing broken go/defer statements.
2. In this case we were failing to swap in the correct ast.Node in for
the *ast.BadStmt because we were only looking
for *ast.BlockStmt (and *ast.CaseStmt has no block).
3. After 2), we weren't returning an error so the fix() code thought
it should recurse.
Fix 2) by using reflection to swap AST nodes in a generic way. Perhaps
a bit overkill in this case, but I happened to have already written
this for an upcoming change, so I just pulled it in to fix this bug.
Fix 3) by returning an error if we fail to swap the AST nodes.

Now we will offer function literal completions when we know the
expected type is a function. For example:
sort.Slice(someSlice, <>)
will offer the completion "func(...) {}" which if selected will
insert:
func(i, j int) bool {<>}
I opted to use an abbreviated label "func(...) {}" because function
signatures can be quite long/verbose with all the type names in there.
The only interesting challenge is how to handle signatures that don't
name the parameters. For example,
func HandleFunc(pattern string, handler func(ResponseWriter, *Request)) {
does not name the "ResponseWriter" and "Request" parameters. I went
with a minimal effort approach where we try abbreviating the type
names, so the literal completion item for "handler" would look like:
func(<rw> ResponseWriter, <r> *Request) {<>}
where <> denote placeholders. The user can tab through quickly if they
like the abbreviations, otherwise they can rename them.
For unnamed types or if the abbreviation would duplicate a previous
abbreviation, we fall back to "_" as the parameter name. The user will
have to rename the parameter before they can use it.
One side effect of this is that we cannot support function literal
completions with unnamed parameters unless the user has enabled
snippet placeholders.

an interface, we will suggest literal candidates that implement the
interface.
The literal candidates have a lower score than normal matching
candidates, so they shouldn't be disruptive in cases where you don't
want a literal candidate.
This commit adds support for slice, array, struct, map, and channel
literal candidates since they are pretty similar. Functions will be
supported in a subsequent commit.
I also added support for setting a snippet's final tab stop. This is
useful if you want the cursor to end up somewhere other than the

Fortunately, go/packages does a great job handling edge cases so gopls
