[PromanSEW]

Please add support for global template variables without ugly hacks as

@import java.lang.Boolean; val isAdmin = Templates.isAdmin(request)

Any news about this feature? Using template parameters is not a nice solution, if you don't want to use hacks. Just allow @val tmp = SomeClass.meth(), so it works with @import well, where is the problem? Twirl template should be functiontal-oriented (like Scala) HTML without imperative variables? Please explain

I think the reason this is not supported is because no one took time to implement it.
I put

• Support for variables #89

on the Play 3.1 roadmap, if time allows I can look into that, it shouldn't be really hard I guess, the parser needs to be adjusted.
@PromanSEW if you have time to look into that I would review a pull request.
