In order to see where the "expected operand" syntax error is coming from
(it could be many places), add a panic
at the top of the error handling parser methods in
go/src/cmd/compile/internal/syntax/parser.go's error handling routines,
which may
be called variously parser.error(), parser.syntaxErrorAt(),
parser.errorAt(), parser.error_at(), or parser.syntaxError(), or
errorExpected() depending
on your Go version. The panic will give you a stack trace, and you can go
from there. e.g.
func (p *parser) error_at(pos src.Pos, msg string) { // for go1.9.7, this
is line 112 of parser.go
panic("claygod's custom debug statement: error_at where??") // add this
line
...
