CTFE may be necessary to determine the type of an Expression, for 
example `mixin(f())` needs to evaluate `f()` to a string, but 
that is handled by semantic analysis. But when you have a call to 
template function `f` like `f(x)`, you only need to know the type 
of `x`, not evaluate `x` to a value at compile time.
