Subject:

t/lex_hinthash.t is storing ArrayRef in hints hash %^H

It is just a unit test so not a big deal but just realized that this unit test t/lex_hinthash.t is storing some Ref values in %^H 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. https://perldoc.perl.org/perlpragma.html#Implementation-details See also my Lexical::Hints module for a clean work-around for this (annoying) limitation with %^H.

of course Lexical::Hints is a Damian Conway module :-) bad copy/paste in the previous message

After reading it a second time, this seem a perfectly use case and the whole test is using that specific hash hint behavior. we should close this case sorry for the noise nicolas On Thu Dec 20 15:29:28 2018, atoomic wrote: Show quoted text
