I don't see a concrete issue, just found it tempting... raising hand-

None that I know of, but I suggest testing with dir, globals, locals
and '__' enabled (which I haven't done yet), as spotting possible
flaws should be easier. If you can get BOM+encoded garbage tested (see

This one fails in lots of interesting ways when you juggle keyword-
exprs = [
'evoque("hmm", filters=[unicode.upper ] ,src="/etc/python2.5/

You're welcome! Don't worry about the beer, I'd only consider a real
promise if it involved chocolate :D
