in thread Readonly oddity

use 5.014; use strict; use warnings; use constant FOO => [ qw(BAR BAZ) ]; push @{FOO()}, qw(BOO HAHA); say join " ", @{FOO()}; @{FOO()} = split / /, "what are you using such constants for?"; say join " ", @{FOO()};
Oh, yeah, also I don't like that you have to add () to those constants in some cases.

    If that was a perceived as a real problem, it would be a pretty trivial fix to constant to have it apply the READOLY flag (per Internals::SetReadOnly()).

    The fact that no one has bothered probably means that most people don't bother to jump through the hoops required to modifiy constants.

    Well, obviously, don't do this. The idea is not to make it impossible to make modifications to FOO, but rather to make it stand out like a constant so that it gets used as a constant.
