Yes, I think so too. In a typed language, you would probably declare an
abstract type for the stack and not provide any kind of matching pattern
for it. This would force people to handle the stack by printing, and there
would be no matching on it at all.

Mimicking this behavior in Erlang is probably the sane behavior in this

I also like Richard's point: matching on the stack will eventually get you
into trouble.
