Thanks - that is good to know and maybe should be documented. Given
that much of the rest of the conf file takes arbitrary perl code, it
wasn't obvious to me that we were leaving the perl paradigm here.

It may be even better to add if it is pretty easy, since at least when
I see the $<variable>, I'm usually thinking either perl or bash
variables - both of which recognize the brace construction. So that
would eliminate such hopefully understandable confusion.
