(lestrrat) Re(2): Accessing Constant Hashes

[lestrrat]

I personally would recommend using a constant if there's a possibility of constant folding:

    #!/usr/local/bin/perl
    use O qw/ Deparse /;
    use constant CONDITION => 0;
    if( CONDITION ) {
        print "condition true\n";
    } else {
        print "condition false\n";
    }

    __END__
    ## and here's the output. notice that there are
    ## no if's
    me@myhost> ./test.pl
    ./test.pl syntax OK
    sub CONDITION () {
        package constant;
        $scalar;
    }
    print "condition false\n";;

Otherwise I guess I could care less, but I use it more for a mental note than anything else -- it makes me aware that this value should be a constant
