From jarausch@numa1.igpm.rwth-aachen.de

The perlop manpage says
"++" and "--" work as in C. That is, if placed before a
  variable, they increment or decrement the variable before
  returning the value, and if placed after, increment or
  decrement the variable after returning the value.

but
print "is defined\n" if defined($H{'x'}++);

# prints is defined
What did I miss ?

P.S. I know that I can do without 'defined' here even with -w,
  so it's not urgent.
