Build error with multiple var declaration inside anonymous func

[Hector Jusforgues]

godebug fails to build some code with multiple var declaration : https://github.com/hectorj/godebug/blob/multiple-var-declaration/testdata/single-file-tests/multiple-var-declaration-in.go

If you run the tests on that branch with -accept=true, it fails like this :

--- FAIL: TestGoldenFiles (4.39 seconds)
    endtoend_test.go:204: Golden file multiple-var-declaration-out.go failed to run under 'go run': exit status 2
        # command-line-arguments
        testdata/single-file-tests/multiple-var-declaration-out.go:21: undefined: y
        testdata/single-file-tests/multiple-var-declaration-out.go:21: undefined: err
        testdata/single-file-tests/multiple-var-declaration-out.go:25: undefined: y
        testdata/single-file-tests/multiple-var-declaration-out.go:27: undefined: err
        testdata/single-file-tests/multiple-var-declaration-out.go:29: undefined: err
        testdata/single-file-tests/multiple-var-declaration-out.go:31: undefined: y

But the "in" code is valid

I can second this, as I just ran into a number of "undefined" errors, and modifying my code from

var (
    x = 1
    y = 2
)

to

var x = 1
var y = 2

fixes it.

Wow, that's surprising behavior. Thanks for reporting this and thanks for the clear test case!
