LV for lvalue

LV makes lvalue subroutines easy and practical to use. It’s inspired by the lvalue module which is sadly problematic because of the existence of another module on CPAN called Lvalue. They can get confused on file-systems that have case-insensitive file names.

LV comes with three different implementations, based on VariableMagic, Sentinel and tie; it will choose and use the best available one. You can force LV to pick a particular implementation using

$ENVPERL_LV_IMPLEMENTATION = 'Magic'; # or 'Sentinel' or 'Tie'

The tie implementation is the slowest, but will work on Perl 5.6 with only core modules.
