Sorry if this is old news. I don't remember anybody reporting this, but I don't follow c.l.py as closely as I used to.

I've been writing a lot of C++ lately and my mind is stuck in limbo somewhere between C++ and Python. I inadvertently wrote the following:

x = 0 while x < 10: # do something ++x

Interestingly, this runs, it just never terminates! Looks like somehow ++x is being parsed as "+0 + x". Shouldn't this construct be flagged as a syntax error?

This happens with both 2.1 and 2.2
