> Traits dont allow $ in identifiers where normal classes do
> ----------------------------------------------------------
>
> Key: GROOVY-6862
> URL: https://issues.apache.org/jira/browse/GROOVY-6862
> Project: Groovy
> Issue Type: Bug
> Affects Versions: 2.3.0, 2.4.3
> Reporter: OC
> Labels: traits
>
> looks like traits are stricter than the "normal" groovy when an identifier
> happens to contain the dollar sign:
> {code}
> 252 /tmp> <q.groovy
> trait Test {
> static foo_ok() { println 'trait non-$ OK' }
> static foo$oops() { println 'trait $ OK' }
> }
> class Foo implements Test {
> static foo$ok() { println 'class $ OK' }
> }
> Foo.foo$ok()
> Foo.foo_ok()
> Foo.foo$oops()
> 253 /tmp> groovy q
> class $ OK
> trait non-$ OK
> Caught: groovy.lang.MissingMethodException: No signature of method: static
> Foo.foo$oops() is applicable for argument types: () values: []
> Possible solutions: foo$ok(), foo_ok()
> ...
> {code}
