I've grepped the first lines of a large project's source files for
instances of the string perl as a word. Sorted, ranked, and slightly
edited, the results can be seen below. What I am wondering is that can
anything general, independent of context be said about the invocations?
For example, is the 'use warnings;' pragma better than launching with
-w? Same for launching perl via '#!/usr/bin/env perl' rather than
'#!/usr/bin/perl' instead? What about a leading whitespace like with
'#! /usr/bin/perl' instead of '#!/usr/bin/perl' ?
Regards,
Lars
