atomo programming language (fork of alex's atomo) — http://atomo-lang.org/
@class: now uses an optional for extending a given object (defaults to Object)
Added initial class-objects system documentation. Closes #9.
provide a @pretty method for class-objects created with @(class: Dispatch)
conversion to patterns is now called @to: rather than @as: to indicate the possibility of failure
corrected @\ macro; first role doesn't have to be a dispatch
