Meh, I don't see this as really a problem or unexpected -- depending on 
how you look at the feature.

In general, anyone who wants to use this technique would know to mixin 
the string in the function they are going to use it.

I'm not saying the proposed DMD update and DIP isn't worth it, as even 
with the better call syntax, this is going to tax the CTFE engine hard, 
compared to what the compiler deals with (and that code already is 
there). But it's worth exploring how far we can get with this idea, to 
see the limitations and benefits. Maybe it solidifies the position that 
we need it in the language instead of the library.
