perl CAN be easy, just like english can. but with such a rich
syntax and broad vocabulary, they're both widely useful and
powerful in getting their respective jobs done.

complex perl is not likely to be easy at all; just as english
grammar can perplex and distract, so, too, can higher
abstractions of perl.

how many lines of C would you need to do the work of a
single-line script like
	perl -ne '/^\s*#/ && next; (! /\S/) && next; print;' < file
anybody care to guess? C has its place -- a well-written C
program will outrun a well-written perl program almost every day
of the week... but the perl program reaches deployment well
ahead of the C executable. (and of course, perl is written in
C!)

once you know most of it, you'll be amazed at how much power
there is in just a few perl expressions -- which is why mr. wall
created the beast in the first place.
