No, there are two lists: typedargslist and varargslist. The latter is only used in lambda functions, which don't support type annotations (yet another twist to remember when it comes to function calls). > Now that Python is moving to a PEG parser, could it be simplified? Perhaps, but that's not really the point I wanted to make. If it's difficult to spell the correct syntax in a parser grammar, then humans will have trouble understanding it as well, esp. people new to Python. -- Marc-Andre Lemburg eGenix.com Professional Python Services directly from the Experts (#1, Apr 20 2020) >>> Python Projects, Coaching and Support ... https://www.egenix.com/ >>> Python Product Development ... https://consulting.egenix.com/ ________________________________________________________________________ ::: We implement business ideas - efficiently in both time and costs ::: eGenix.com Software, Skills and Services GmbH Pastor-Loeh-Str.48 D-40764 Langenfeld, Germany.
