Like a lot of the Perl language, many of its operators have been borrowed from a number of different sources, including C, Bourne shell, and Fortran.
Perl gets most of its operators from C, including the increment operators complete with their unique prefix and postfix distinctions. Perl also has unique string operators, including override operators to create your own quotation marks for cases where your strings will have quotes imbedded within them.
There are also special operators for dealing with regular expressions, files, and lists, filling out its menu of operators as one of the most complete in any language.
