Well, i'm currently playing with std.variant so it can be 
ctfe-friendly. And it works pretty much, however i need to use 
T.stringof.ptr/length instead of typeid (typeid is ctfeable), and 
i'm not sure if it's good for performance in runtime. So for type 
comparison i'd like to compare TypeInfos in rt, and T.stringof in 
ct. Using both with rt if will likely generate more code.
