Re: Pre-increment *and* Post-increment

Perl follows the C convention for the increment/decrement operators, or nearly so. ++$foo++ is undefined because only one *-ment op is allowed per variable in a statement. Would you like that to do (++$foo)++, or ++($foo++) ? It would make a difference, but there is nothing in the grammar to distinguish them.

`(++$foo)++` and `++($foo++)` don't work either, for reasons mentioned by ambrus.	[reply] [d/l] [select]
