Bug #74525 for Constant: Make complex data structures immutable

Subject:

Make complex data structures immutable

If you use Const::Fast and define a constant as an arrayref or hashref, it will make the whole data structure immutable. I think it would be handy if the constant pragma did this. Then you could: use constant HASHREF => { a => 1, b => 2 }; and then do HASHREF->{a} and know that it's immutable. You can do the above now, but you can change the contents of the referenced hash.

Sorry, but because constant.pm really is a core module, its development happens on perl5-porters, so I suggest discussing this feature there, or opening a ticket on Perl RT with perlbug. -- Sébastien Aperghis-Tramoni Close the world, txEn eht nepO.
