Here's another one:
I've created a method that returns an array of its own class:
anArray: aQuantity

a := Array new: aQuantity.

I've been using accessors for every instance variable, and even using them
internally.
I have to admit, because of the need to preface every method call with
self, it makes the code look less clean.
I've also ended up with what seems to be an odd construct:
clear
self myCollection
the
iterator ends up missing items because it's changing as it goes. Hard for
me to believe this is a bug, but that's what it looks like to me.
