Re^2: Pre vs Post Incrementing variables

[JavaFan]

Technically, the operand evaluation order for the comma operator in list context is not defined,

The perlop manual page says in the section about the comma operator:

In list context, it’s just the list argument separator, and inserts both its arguments into the list. These arguments are also evaluated from left to right.

This has been in perlop since April 2006.
