    Something that is just as fast (slightly faster) than use constant, that can be localized, and that is neat, is to create a reference or alias to a non modifiable variable. Try this:
    local *CONST = \23.34234334234;
    Try to modify it. You can't. Declare it at the top of your program and it is there for life. Put it in a sub and it stays around for the life of the sub. See 75935 buried way at the bottom of this node.

    my @a=qw(random brilliant braindead); print $a[rand(@a)];
