They now show the correct name, the byte offset on the line, and context for the failed evaluation.
Before:
template: three:7: error calling index: index out of range: 5
After:
template: top:7:20: executing "three" at <index "hi" $>: error calling index: index out of range: 5
Here top is the template that was parsed to create the set, and the error appears with the action
starting at byte 20 of line 7 of "top", inside the template called "three", evaluating the expression
<index "hi" $>.
Also fix a bug in index: it didn't work on strings. Ouch.
Also fix bug in error for index: was showing type of index not slice.
The real previous error was:
template: three:7: error calling index: can't index item of type int
The html/template package's errors can be improved by building on this;
I'll do that in a separate pass.
Extends the API for text/template/parse but only by addition of a field and method. The
old API still works.
Fixes#3188.

This change updates CL 6576057 for exceptional cases where
return values from Syscall/RawSyscall functions are used.
The system calls return 32-bit integers. With the recent change
in size of `int' in Go for amd64, the type conversion was not
catching `-1' return values. This change makes the conversion
explicitly `int32'.

FormatSelections tries to call a nil function value if lw is nil
and the final entry in the selections array is non-nil. Luckily,
this doesn't actually happen in practice since godoc doesn't use
this combination (no line numbers, but with selections).

The previous implementation was a mess with invariants
maintained inconsistently. Essentially reimplemented
the package:
- used a circular list as internal representation for
significantly simpler implementation with fewer
special cases while maintaining the illusion of
a nil-terminated doubly linked list externally
- more precise documentation
- cleaned up and simplified tests, added test case
for issue 4103.
No changes to the API or documented semantics.
All this said, I would be in favor of removing
this package eventually. container/ring provides
a faster implementation and a simpler and more
powerful API.
Fixes#4103.

In two cases, registers were allocated too early resulting
in exhausting of available registers when nesting these
operations.
The case of method calls was due to missing cases in igen,
which only makes calls but doesn't allocate a register for
the result.
The case of 8-bit multiplication was due to a wrong order
in register allocation when Ullman numbers were bigger on the
RHS.
