You have to explicitly force ctfe with context, it is never done 
automatically, and if it fails, the build will fail and you get a 
compile time error.

So if you write

enum f = foo();

or

static f = foo();

or similar initializations and the build succeeds, you know it 
got ctfe'd. Otherwise, it wasn't.
