I was curious about why were logging errors during type-checking in tests, and the answer turned out to be a bit more sinister than I expected. We were getting type error messages without filepaths, so I tried to reproduce it in the playground and wasn't able to. I realized that these errors were coming from were coming from the "fixed" version of the AST that we pass to the type checker. Adding fake positions to our fake Cond statements trivially fixes the logging issue, but it does nothing to handle the fact that the error makes no sense to the user - because it applies to something that's not in the source code. I figured we have two options: (1) skip type errors for all packages with "fixed" ASTs, or (2) add something to the error messages to indicate that the source code may not match. Starting with (1) here, and if it becomes a problem, we can move to 2. All ASTs that we fix have *ast.BadExpr in them, meaning that, by definition they have parse errors which we will preferentially show those errors to users in diagnostics (so I'm not sure how to test this).

Go Tools
This subrepository holds the source for various packages and tools that support the Go programming language.
Some of the tools, godoc and vet for example, are included in binary Go
distributions.
Others, including the Go guru and the test coverage tool, can be fetched with
go get.
Packages include a type-checker for Go and an implementation of the Static Single Assignment form (SSA) representation for Go programs.
Download/Install
The easiest way to install is to run go get -u golang.org/x/tools/.... You can
also manually git clone the repository to $GOPATH/src/golang.org/x/tools.
