Variable::Expand::AnyLevel enables to expand variables which exist at any level. (level means same as Carp or PadWalker)
Expand variable in $string which exists in $peek_level. $peek_level is same as caller().
If stringify option specified(it is default) $string is correctly expanded. For example,
my $aa = 'aa';
my $result = $expand_variable('$aa 123', 0);
$result is expanded 'aa 123'
If stringify option is set to '0', $string is not expanded.
my $aa = 'aa';
my $result = $expand_variable('$aa 123', 0, { stringify => '0' });
$result is undef.
available options are as follows
stringify: stringify variable(1) or not(0). default value is 1
