It depends. When linking unused functions can be removed by 
-gc-sections, but only when linking an executable.

But obviously if you use it at runtime then the linker won't 
remove it. If you want to ensure that it never gets called at 
runtime, put a `assert(__ctfe);` at the beginning of the function.

There was a discussion some time ago about having an attribute(?) 
to disable codegen for particular functions (e.g. code for 
generating string for string mixins), but i'm not sure what 
became of that.
