This is much better than having to mixin everywhere. A couple of 

1) Can this be put in a module so that you don't have to 
mixin(enableInterpolation) but instead "import interp = 
std.interpolation;" or something similar?

2) This would unfortunately pollute the namespace and in code 
that uses interpolation heavily, you'd have to rename it to 
something non-clashy which I can see being quite annoying and a 
maintenance burden if it turns out to be a common thing to do. 
Maybe if it's just standardly called "interp" it may be alright
