That's my feeling too, in general.

Is my specific usage style OK -- many instance methods from many classes 
calling shared state-less methods from a common class? Or does it have some 
kind of code smell? Any thought on whether traits (simply mixing them in on 
the instance side) would be a preferred approach to this?

Foo>>m1
  Library doX: iVar1 with: iVar2

Foo>>m2
  Library doZ: iVar2

Bar>>m3
  Library doX: iVar7 with: ivar8

Library class>>doX: anX with: aY

Library class>>doZ: aZ
