NAME
    Devel::LexAlias - alias lexical variables

SYNOPSIS
     use Devel::LexAlias qw(lexalias);

     sub steal_my_x {
         my $foo = 1;
         lexalias(\&foo, '$x', \$foo);
     }

     sub foo {
         my $x = 22;
         print $x; # prints 22

         steal_my_x;
         print $x; # prints 1
     }

DESCRIPTION
    Devel::LexAlias provides the ability to alias a lexical variable in a
    subroutines scope to one of your choosing.

    If you don't know why you'd want to do this, I'd suggest that you skip
    this module. If you think you have a use for it, I'd insist on it.

    Still here?

    lexalias( $coderef, $name, $reference )
        "$coderef" refers to the subroutine in which to alias the lexical

        "$name" is the name of the lexical within that subroutine

        "$variable" is a reference to the variable to install at that
        location

BUGS
    lexalias delves into the internals of the interpreter to perform it's
    actions and is so very sensitive to bad data, which will likely result
    in flaming death, or a core dump. Consider this a warning.

    There is no checking that you are attaching a suitable variable back
    into the pad as implied by the name of the variable, so it is possible
    to do the following:

     lexalias( $sub, '$foo', [qw(an array)] );

    The behaviour of this is untested, I imagine badness is very close on
    the horizon though.
