Using templates to introspect and manipulate types is like using a hammmer's flat back to remove a nail.
It _can_ be done but with an absurd amount of work.
You just have to remove all of the wall around the nail by pounding it until the wall has around the nail is disintegrated :)

This is not an exaggeration.

Templates used for introspection (or anything else really that's modestly complex) are equally hard to reason about for compilers and for programmers. I guess programmers have an advantage when it comes to _efficient_ pattern recognition.

Could AST macros replace things like @safe/@nogc and enable the user to create their own (like a @supersafe that disallows @trusted)?
