Ok. What I want to do is to define a class in my namespace that gather some
matrix-like classes so that I can define a set of common functions for them.
Initially I want matrix and ExpressionSet objects, and possibly add array
objects later.
Union classes seem to be exactly the way to go, but maybe there is an
alternative?

I guess a quick fix for devtools, would be to wrap the cleanup procedure
into a try or tryCatch (Hadley?).
