Remember, Perl was a successor to sh (among other things). From perldoc perl
<blockquote>
Perl combines (in the author's opinion, anyway) some of the best
features of C, sed, awk,
and sh, so people familiar with those languages should have
little difficulty with it.
(Language historians will also note some vestiges of csh,
Pascal, and even BASIC-PLUS.)
Expression syntax corresponds closely to C expression syntax.
