Do you happen to have concrete questions about them which aren't answered by their docstrings? > Pattern matching is a useful facility, but pcase is woefully hard to use > correctly, as the existing (mis-)usage shows. I obviously can't judge fairly how hard it is to use, but I don't find any of the examples posted here as evidence of problematic use and even less misuse (they look perfectly correct to me). Could you clarify what you find problematic in those uses? Stefan
