cmd/compile: validity of program depends on method declaration order

[griesemer]

https://play.golang.org/p/WCktUidLyc_3 is accepted while the equivalent program https://play.golang.org/p/Z-B9rBhYILd fails with an error. The only difference is the order of the method declarations.

Esoteric case; recording this so we're aware of it.

Hey @andybons, that first snippet doesn't load.

[andybons]

Yes it does. The trailing underscore gets stripped with some URL parsers (like in Gmail or GitHub). Make sure it’s there and it should load.

[bradfitz]

Maybe we shouldn't generate snippets with trailing underscores then.

(Seems to work with gccgo.)

Pushed new version of play and updated original comment with link that is properly linkified by GitHub. Sorry to derail this bug, Robert.
