Greetings monks,

The code chop foreach qw/foo bar baz/ will die with 'Modification of a read-only value attempted'. This is good.

However, if I make my own chop function and run it on the that literal list like so, printing what's actually getting chopped:
sub mychop(\$) { chop ${shift()} } foreach my $thing (qw/foo bar baz/) { print "$thing -> "; my $c = mychop $thing; print " $thing,$c\n"; }
Instead of dying with 'read only value' as I would expect, it prints:
foo -> foo,o bar -> bar,r baz -> baz,z
Can anyone enlighten me as to why this is?
