I disagree. For normal Perl programming, you will never care about how a scalar is implemented. For normal C programming, the size of an int is critical! (I know this because I got hit by the fact that Win32 has a 16-bit int and Unix a 32-bit int.)

OOP is about using objects, as well as adding objects. It's a paradigm shift, not just a few new keywords and syntax goodies. People were writing OO code before OO existed and people are writing procedural code with OO syntax.

We are the carpenters and bricklayers of the Information Age.

Don't go borrowing trouble. For programmers, this means Worry only about what you need to implement.
