With heavy ctfe code generation usage is it possible to have the
d compiler output the source code after all mixin templates have
been "used"? This way it is easier to visually check for errors

Hello, I am trying to using static opCall instead of the default

When I run it, I got "Error: need 'this' to access member A".
How to fix it?

T[] A;
int num;

I just use

which covers both cases and is pretty intuitive too.
