Paul King commented on GROOVY-8412:
-----------------------------------

I remove the code which previously treated instanceof and !instanceof the same. But we haven't put in any support for the negated case as yet.

> {{maybeFile instanceof File ? maybeFile.canonicalPath : maybeFile.toString()}} sees maybeFile as type {{File}} in the true expression.  However, {{!(maybeFile instanceof File) ? maybeFile.toString() : maybeFile.canonicalPath}} does not offer the same support for the else expression.  The same applies if either were written long-form with if/else.
