Welcome to template bloat hell.

IIRC diet templates is very template heavy, it makes tons of (D) 
template instantiations and the linker has a lot of work because 
of that. It is even worse with LDC.

If there is runtime diet parser(which I doubt) instead of default 
`render!` template you can move diet to it to save on compile 
time.
