How about crystallize for permanent, and freeze/unfreeze for reversable? The only problem is that I'll never be able to remember if crystallize is with one l or two. Hmmm.... let me look that up. Eek! It can be either way! Although two l's seems to be the standard form. Or, if you're a Star Wars fan, how about leaving freeze for permanent, and have carbonitify/decarbonitify for reversable? Then I could have a business card like: Nathaniel Talbott Object Technology Specialist Ruby Bounty Hunter <stupid grin> Oh, and Merry Christmas to everyone. This list is just as cool as Ruby itself. Everybody keep up the good work, and lets take over the world (so I can write Ruby instead of Java)! Nathaniel <:((>< + - - + - - | RoleModel Software, Inc. & | EQUIP VI | The XP Software Studio(TM) |
