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.
