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.
