Yea, the trouble with string mixins is that they're ugly enough people 
don't like to use them.

I'd argued in the past for a way to tag a CTFE-able string-returning 
function as being intended for mixing-in, so you could omit the 
"mixin(...)" part. But we only ever got it for template mixins. Allowing 
it for string mixins was too controversial. :(

I dunno, maybe even a string mixin sugar as simple as this would be a 
big help:

mixin!func(args to func here)

ie:

mixin!interp("Some string here")

But I'm guessing the ship's ling since sailed for anything like that.
