*sigh*, If D allowed something like this:
mixin string map() { return "code here"; }
map();
As an alternative to or intead of this:
string map() { return "code here"; }
mixin(map());
As I've suggested before (it only got accepted for template mixins, not
string mixins), then map's string-style predicates could be made to be
evaluated in the proper context without screwing up map's standard interface
by requiring it to be called with "mixin(...)".
