Acme::constant lets you make inconstant constants, just like the constants the users of ruby or opera (before opera 14, that is) already enjoyed.

unlike perl constants, that are replaced at compile time, acme constants, in true dynamic programming language style, can be modified even after declaration.

just like constants generated with standard use constant pragma, the constants declared with use acme::constant don't have any sigils. this makes using constants easier, as you don't have to remember what sigil do constants use.
