Christian> Well, the (bad) effect of this patch is that you cannot run Christian> PythonWin any longer unless Mark either supplies an updated Christian> distribution, or one corrects the two barfing Scintilla Christian> support scripts by hand. Zope has the multi-arg append problem as well. It wasn't clear to me where all the problems resided. I've been thinking mostly about the problem in Python code. Thankfully Tim released checkappend last night! Even after getting rid of all the cases it found I was still getting some flaky tracebacks which suggest to me that some C code makes the same sort of assumptions. I've never labored under the assumption that append would take multiple arguments. I was mildly surprised to find an instance of this crop up in my own code...
