This won't work without a way to mark `genStuff` as CTFE only. Which
doesn't exist currently.
Compiler has to know that a given execution context is CTFE only
otherwise disallowed.
1. Any proposals to mark a function as CTFE only?
No, this is something that should've been done a while back.
The main concern is that you can get a linker error if you don't emit
a function that was called.
Actually, in your example, don't see the problem.
'mixin' operates to provide text to the compiler _prior to_ run time.
Therefore, even if 'genStuff()' has a run-time (as well as) compile-time
meaning,
the use of mixin should force the compile-time meaning to be taken.
So no ambiguity?

genStuff will still compile into the binary.
The error happens when it tries to do that, not when it tries to run it
for the string mixin.
