Re: [Xotcl] Mixins in XOTcl

what about just extending the usually interfaces with new arguments, such as:

A mixin X A mixin add Z 3 A mixin add Y end A mixin delete Y A instmixin add T 1 A superclass B A superclass add C

That's pretty much what I was thinking:

A mixin X ;# current behavior A mixin -set X ;# A mixin X A mixin -set X Y Z ;# A mixin {X Y Z}

A mixin -add X ;# A mixinappend X

Using -set, -add and -delete feels more Tcl-ish. Also, it is somewhat bad style to name a class 'add', but even worse style to name it '-add'. By using options, I can still mixin a class 'add' into a definition. Preventing me from mixing in a class '-add' is a good idea, for other reasons.
