Finding a stray int (or whatever) that doesn't appear to be live at a
particular point and re-using it for something unrelated isn't
necessarily good coding practice either.  This can confuse someone who
is quickly scanning the code - especially if the variable name was
mnemonic and the re-use doesn't match it's name.

It's unfortunate that C doesn't have any way to define the end of a
variable's scope (or lifetime) apart from blocks.
