Oh - I don't think my whole post was rubbish, but that note sure was (and due to quick-posting). I'll cite myself on the very same topic some weeks ago:
Rescanning happens /after/ argument substitution [ 16.3.4.-1 ] and the replacement
restrictions for rescanning [ 16.3.4-2 ] do not apply for argument substitution [
16.3.1 "A parameter in the replacement list [...] is replaced by the corresponding
argument after /all/ macros contained therein have been expanded" ].

I hope to understand more after reading your reply to my Chaos questions (no need to hurry).
BTW. should I better ask somewhere publicly (the seemingly dormant Sourceforge forum of the chaos-pp project, perhabs) rather than in private email?
