Then when you call that:
f(a < b)
This is a little dangerous as it looks like an ordinary
expression but has to somehow affect symbol scoping.
That's true, and that was one reason I suggested some kind of
template mixin literal. On the other hand, that's just an extreme
version of what happens with lazy, where at the call site you
can't tell that the argument side effects are not produced
immediately. Without experience with features like this it's hard
to tell if their usefulness pays for their cost, but it seems to
me that something like this could make for very powerful macros.

I was not aware of the token strings, is that new? Boy, I really
should spend more time around here. That's an excellent
suggestion, although I think these "mixin parameters" we are
discussing are more like mixin template parameters than mixin
string parameters.
