Other Operators and Functions (Learning Perl, 3rd Edition)

B.8. Other Operators and Functions

Yes, there are more operators and functions than we can fit here, from the scalar .. operator to the scalar , operator, from wantarray to goto(!), from caller to chr. See the perlop and perlfunc manpages.

B.8.1. Transliteration with tr///

The tr/// operator looks like a regular expression, but it's really for transliterating one group of characters into another. It can also efficiently count selected characters. See the perlop manpage.

B.8.2. Here documents

Here documents are a useful form of multiline string quoting; see the perldata manpage.
