[PD] passing integers

how about passing symbols, possibly written as somehow prefixed octal,
hex or binary numbers, and then atoi()/strtol()/sscanf()/whatever()
them to integers?

But I wonder:  if there was a huge amount of different masks generated
during a Pd session, how this would affect the overall performance?
What I mean is that the penalty of symbol hash table slot chaining
could get high.

If this is true, then I wonder:  is the above a viable reason for
giving users a way (like sending a message to pd) to clear symbol
table of currently unused (not bound, etc.) elements?
