The problem is that the regex for the ... in $... and ${...} is the
same, so if you want to match ${foo:bar}, you also have to match
$foo:bar. I'd rather leave $foo constrained to simple variable names,
and require ${} for anything more complex.
I got around that with LaxTemplate at the bottom of this file:
