I don't know. What do you mean by "conditional mixin"?
mixins with guards. see following example. -gustaf
Class Fly -instproc fly {} {puts "[my signature]: yippee, fly like an eagle!"} Class Sing -instproc sing {} {puts "[my signature]: what a difference a day make"}
Class Animal -parameter age Animal instproc unknown args { puts "[my signature]: how should i $args?"} Animal instproc signature {} { return "[self] [my info class] ([my age] years)" }
Class Bird -superclass Animal Class Penguine -superclass Bird Class Parrot -superclass Bird Class Duck -superclass Bird
Parrot tweedy -age 1 Penguine pingo -age 5 Duck donald -age 4 Parrot lora -age 6
Bird instmixin {{Fly -guard {[my age]>2 && ![my istype Penguine]}} Sing} foreach bird [Animal allinstances] { $bird fly }
