I'm doing the same in my UI framework. In addition to being able to 
collect all strings at compile-time, it is also possible to translate 
and verify the existence of strings at compile-time by loading and 
parsing the PO-files with CTFE.

BTW, I never got around to commenting on the string interpolation topic, 
but the inability to translate i"" strings was my biggest practical 
concern. Never really understood the reluctance against lowering to a 
template instantiation, though.
