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.
