Why are parentheses aroung the `expr' sloppy? I had been programming
in C for quite a while before I found out that you could leave the
Parens Out!! All (or almost all) examples in K&R show parentheses
around the expressions, and this is the example that I followed.
( When in doubt, paranthesize??? ).
