Some tasks are too menial for a dedicated script but still too cumbersome even with the many neat one-liner options of "perl -E". This small script fills the gap: various one-letter commands & magic variables (with meaningful aliases too) and more nifty loop options take Perl programming to the command line. Fully imports List::Util. With no program on the command line, starts a pl Shell.

How to "e(cho)" values, including from "@A(RGV)", with single "$q(uote)" & double "$Q(uote)". Same for hard-to-print values:
$  pl  'e  "${q}Perl$q",  "$Q@A$Q"'  one-liner
$  pl  'e  \"Perl",  \@A,  undef'  one-liner

Loop over args, printing each with line ending.  And same, SHOUTING:
$  pl  -opl  ''  Perl  one-liner
$  pl  -opl  '$_  =  uc'  Perl  one-liner

Print up to 3 matching lines, resetting count (and "$.") for each file:
$  pl  -rP3  '/Perl.*one.*liner/'  file*

Count hits in magic statistics hash "%N(UMBER)":
$  pl  -n  '++$N{$1}  while  /(Perl|one|liner)/g'  file*
