CTFE doesn't mean "string mixins using CTFE". It just means CTFE.
(BTW you can do string mixins with templates only, no CTFE, if you
are completely insane).
CTFE without mixins is rather limited form of metaprogramming. You can
basically only initialize some static non-code data, and not much
more. String mixins with templates was the only way to go before CTFE
became possible -- those were the times!
What does yacc do? Build a switch statement via cut-n-paste, define a few
constants, define a few types via cut-n-paste, and initialize some static
data.
Oh and there's no such thing as non-code data, if you are crazy enough:
const byte[] it = buildPositionIndependentCodeAsString(Data);
int i = (cast(int function(int))it.ptr)(42);
