From the keyboard of Johan Vromans <jv@mh.nl>:
:Perl 4.010, System Ultrix/RISC, GCC compiled.
:
:Exhibit 1:
:
:	$a = "1a";
:	$b = $a + 1;
:
:I would have expected an error (or at least a warning).

No, it's always done that -- atoi()d a for the number part.

:Exhibit 2:
:
:	$a = "1a";
:	$a++;
:
:IMHO, the correct value for $a should now be "1b", not 2.

Hmm... in mine as well.  'aa' goes to 'ab'; why shouldn't
'1a' go to '1b'?
