[net.lang.c] i=++i ?= i = ++i

ee163cz (03/12/83)

   The expression "i=++i", if written without spaces, doesn't necessarily
parse as "i= ++i".  The Old Compiler and many of its less legitimate
descendants will try to parse it as "i=+ + i", giving an error, and
possibly (just guessing now) produce "i=+i", or "i=2*i".  The old =+, =-
syntax is STILL around, and occasionally catches me trying to say something
like "i= -1" without the space.  Correction: the compiler doesn't catch
me; the program misbehaves in mysterious ways.
