The main requirement for what can go in guards is not really that it is 
O(1) but that it must be side-effect free.  Which put/2 is not.

Personally I have always considered the process dictionary to be a BIG 
mistake and therefore feel we should do nothing which encourages it, 
like making it accessable in guards. :-)
