In some situations I will use either the default parameter
initialization Chris mentioned, or the closure mechanism that the OP
presented, but only on code that I am optimizing for speed (local
variable lookups, even in nested functions, being much faster than
global or instance lookups).  If it doesn't need to go fast, globals
or instance variables are the way to go.
