I understand, but compared to how I solved the issue
1. it invents an (arguably inferior) parameter passing system, even
though there is one in the language.
2. it picks up all symbols used in $(...) from the caller's context
rather than the callee's context and there is no way to get rid of that
default, because the macro is unscoped.
Fair enough. I think your idea of defining a mini-macro-expansion system
based on CTFE and strings is genius. I also think at the present the
semantics are very unprincipled, and should not be popularized in any
form lest D mixins acquire reputation similar to C macros. Finally, I
think you have the resources to work your idea into a wonderful system
that will be principled, practical, and extremely powerful.
Good luck!
