I'm not 100% sure about that, but it seems a plausible possibility. As long as
you aren't calling the delegate from within the function (your ASSERT function
seems to be, and assert definitely would be), then just accessing the stack
frame data should be OK.

As far as @nogc goes, that is simply an issue with the functions you need to
call. If you need GC functions within @nogc, then you have to obscure and cast.
I think it's possible to argue that assert should allow GC functionality, but
not 100% sure of that. It appears that any inner functions inside a pure
function are also marked pure. Since there's no "unpure" attribute, it's hard
to undo this.
