Well, between
your snippet and
merlyn's,
and a CB comment by
tye,
I've come to a much greater understanding of what's
going on. I think :)
If I'm understanding properly, you could do
anything to the keys in this setting, because
they're just strings and you can't get references to
them to allow their modification, which is how the
values get modified.
That's what my test code suggests, anyway:
#!/usr/local/bin/perl -w
use strict;
my $ref={ a => 'aa', b => 'bb'};
print "The hash, before:$/";
print %$ref;
print qq($/The hash "during":$/);
for (%$ref) {
/[A-Z]/ or $_ = 'x';
print;
}
print "$/The hash, after:$/";
print %$ref;
print $/;
__END__
The hash, before:
aaabbb
The hash "during":
xxxx
The hash, after:
axbx
This is perl, v5.6.0, BTW.
