What bearophile said. The amount of functions that can be CTFE'd 
is increasing everyday.

It *would* though be nice to document it as such (eg $(CTFEable) 
).

That said, it is also kind of like @safe and nothrow: For 
templates, it'll really depend on the arguments: For example, 
Appender!(char*) can be CTFE'd, but chances are it won't work for 
a struct with postblit.

But yes, I think we need to document better.
