You can use perldoc -f for functions and perldoc -v for variables, but there's no similar switch for operators. What you could do is to use this time to learn operators. Sometimes, I use Term::Shell as a personal notebook mechanism. Instead of making postit notes, I write a few subs using my notes. I put together a sample that can get you going. I started with comma, but as you progress, just add a sub for each operator.

package perlop;
use base qw(Term::Shell);

my $obj = perlop->new();
$obj->cmdloop;

use strict;
use warnings;

sub prompt_str {
    my $cwd = 'cwd';
    $cwd =~ s[^\Q$ENV{HOME}\E][~];
    "perlop> ";
}

sub run_comma {

    print <<"EOF";
    
Binary "," is the comma operator. In scalar context it evaluates its l
+eft argument, throws that value away, then evaluates its right argume
+nt and returns that value. This is just like C's comma operator.
In list context, it's just the list argument separator, and inserts bo
+th its arguments into the list. These arguments are also evaluated fr
+om left to right.
The => operator is a synonym for the comma except that it causes its l
+eft operand to be interpreted as a string if it begins with a letter 
+or underscore and is composed only of letters, digits and underscores
+. This includes operands that might otherwise be interpreted as opera
+tors, constants, single number v-strings or function calls. If in dou
+bt about this behaviour, the left operand can be quoted explicitly.
Otherwise, the => operator behaves exactly as the comma operator or li
+st argument separator, according to context.
EOF

    print "\n";
