Re: Nested templates

Yes, that solves a slightly different problem
than my (admittedly somewhat pointless) example,
but it doesn't address the nesting that I'm
after.  I don't do it a lot, but there are key
points where I want to, and I like to be able
to count on it working.  I'd like there to be
an option to new() that says, "Do repeated
substitutions until there aren't any more".

I suspect that would still incur a 'compile'
step each time, but I'd hope it could avoid
the copy from output() and the repeated param()
calls.

Thanks,

Brad
