Hi! Are there any known changes/problems with named groups in Python 2.2 re? Given this: (?P<heading>^\s*(?P<hmarker>=+)\s.*\s(?P=hmarker) $) Python 2.2 reports groups for the nested named parens, while previous versions do not. If this is unexpected, I'll isolate this effect in a little script. Bye, Jürgen
