But that's exactly why you need to try it and see. The more a document
spends on the arcane details of a function (which perldoc does), the more
likely a beginner would get lost in those details and find some other source
of reference.
Instead of the perldoc chomp example of:
while (<>) {
chomp; # avoid \n on last field
@array = split(/:/);
# ...
}
(I consider myself an intermediate Perl programmer, and the above is still a
useless example to me. It never really shows you what chomp does).
How about:
$ll = "A full line here.\n" ;
chomp ( $ll ) ;
# Now $ll = "A full line here." ;
Sure this doesn't cover everything but for a beginner it's an example you
can put your arms around.
