dragonchild has asked for the wisdom of the Perl Monks concerning the following question:
One thing I'm noticing is that gcc has a warning it throws up. But, wouldn't using the C preprocessor be faster and use less memory than constant, especially for large numbers of them? I'm thinking of sites with mod_perl and a large number of hits ...#!/usr/bin/perl -P #define ABC 1 use constant DEF => 1; print ABC, $/; print DEF, $/; ------ $ ./abcd gcc: file path prefix `/usr/ccs/bin/' never used 1 1
Also, what's the difference in using #include vs. require? And, doesn't #define provide first-class macros where there is no real provision for them in Perl?

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