I think another big part of it is that currently, using string 
interpolation requires pulling in a dub package as a dependency. 
Especially in small projects, the difference between "zero 
dependencies" and ">=1 dependencies" is pretty huge. If `interp` 
were in the standard library (std.string, maybe?) it would 
probably see more use than it does now (at least, I'd use it in 
my projects).
