I currently have a perl module I am modifying. I am trying to hook the select builtin and define my own in pure perl. The module has a method called select that looks like this 
sub select
{
 shift
   if defined $_[0] && !ref($_[0]);

 my($r,$w,$e,$t) = @_;
 my @result = ();

 my $rb = defined $r ? $r->[VEC_BITS] : undef;
 my $wb = defined $w ? $w->[VEC_BITS] : undef;
 my $eb = defined $e ? $e->[VEC_BITS] : undef;

 if(select($rb,$wb,$eb,$t) > 0)

I tried to override the builtin select with use subs 'select'; and then defining a 2nd select sub in the same package. I get a "Deep recursion on subroutine "IO::Select::Foo::select"" now (my custom select sub is overridden by the select method sub). How do I override the builtin select package wide and still keep my select method sub (which is public API and cant be renamed)?
