hello, when you do this: use Function::Parameters; use Regexp::Grammars; qr{ <grammar:Sympa::Scenario> }x; you get this Function::Parameters: internal error: $^H{'Function::Parameters/config'} not a hashref: HASH(0x56276feec8c0) at (eval 7) line 1. i'll have time to dig on it at the beginning of 2019 but someone can spot the error before that. regards marc

This is a bug in the implementation of Function::Parameters. The hints hash (%^H) cannot be used to store hashrefs as values, so any implementation that relies on putting hashrefs in %^H is intrinsically broken. See "Implementation details" in the perlpragma manpage. See also my Lexical::Hints module for a clean work-around for this (annoying) limitation with %^H. Damian
