String interpolation in templates

Currently Twirl does not support string interpolation in templates, I think mostly because simple string interpolation can be done with Twirl itself, like Hello, @name!. But more complex string interpolators cannot be substituted with Twirl. The sample of such interpolator is a translating interpolator at my project, Scalingua. Currently we have to write

  @(t"Hello, world!")

Could Twirl compiler support shorter and cleaner version of it, something like

  @t"Hello, world!"

This is a pretty minor issue, of course, but these parentheses looks ugly, and adding string interpolation syntax should not break any existing code.

I think that introduces some ambiguity, though, or at least a backwards-incompatible syntax change. Now @t"foo" is an interpolated string, whereas before it was a variable followed by a literal quoted string.

closing since there’s no clear way I see to introduce this new syntax without breaking changes.
