Shift Operators Binary "<<" returns the value of its left argument shifted left by the number of bits specified by the right argument. Arguments should be integers. (See also Integer Arithmetic.) Binary ">>" returns the value of its left argument shifted right by the number of bits specified by the right argument. Arguments should be integers. (See also Integer Arithmetic.) Note that both << and >> in Perl are implemented directly using << and >> in C. If us

$( The real gid of this process. If you are on a machine that supports membership in multiple groups simultaneously, gives a space separated list of groups you are in. The first number is the one returned by getgid() , and the subsequent ones by getgroups() , one of which may be the same as the first number. However, a value assigned to $( must be a single number used to set the real gid. So the value given by $( should not be assigned back to $( without being forced numeric, such as by adding

NAME DESCRIPTION NAME Memoize::ExpireTest - test for Memoize expiration semantics DESCRIPTION This module is just for testing expiration semantics. It's not a very good example of how to write an expiration module. If you are looking for an example, I recommend that you look at the simple example in the Memoize::Expire documentation, or at the code for Memoize::Expire itself. If you have questions, I will be happy to answer them if you send them to mjd-perl-memoize+@plover.com.

fc EXPR fc Returns the casefolded version of EXPR. This is the internal function implementing the \F escape in double-quoted strings. Casefolding is the process of mapping strings to a form where case differences are erased; comparing two strings in their casefolded form is effectively a way of asking if two strings are equal, regardless of case. Roughly, if you ever found yourself writing this lc($this) eq lc($that) # Wrong! # or uc($this) eq uc($that) # Also wrong! # or $this =~
