Constants are different than normal variables, so I like how use constant constants look differently (due to lack of a sigil). Isn't that one of Perl's mantras?

Readonly uses tie. Tied variables are slower, and they behave erratically in a few situations.

On the other hand, Readonly works on types other than scalar.
