NAME

List::Util::MaybeXS - List::Util but with Pure Perl fallback

SYNOPSIS

  use List::Util::MaybeXS qw(
    any all
  );

DESCRIPTION

This module provides the same functions as List::Util, but falls back to pure perl implementations if the installed List::Util is too old to provide them.

Picking between List::Util's XS accellerated functions and the PP versions is done on a per-sub basis, so using this module should never result in a slowdown over using List::Util directly.

FUNCTIONS

all
any
first
min
max
minstr
maxstr
none
notall
product
reduce
sum
sum0
shuffle
uniq
uniqnum
uniqstr
pairs
unpairs
pairkeys
pairvalues
pairmap
pairgrep
pairfirst
tail

DIFFERENCES FROM List::Util

As the subs provided are implemented in perl, there are some minor differences with the interface.

@_ in blocks

Inside a callback block (such as any { }), @_ will be empty when using the pure perl implementation. With the XS implementation, the outer @_ will be visible. Under the perl debugger, the XS implementation will also not be able to see the outer @_.
