=head1 NAME
ExtUtils::ParseXS::Eval - Clean package to evaluate code in
=head1 SYNOPSIS
  use ExtUtils::ParseXS::Eval;
  my $rv = ExtUtils::ParseXS::Eval::eval_typemap_code(
    $parsexs_obj, "some Perl code"
  );
=head1 SUBROUTINES
=head2 $pxs->eval_output_typemap_code($typemapcode, $other_hashref)
Sets up various bits of previously global state
(formerly ExtUtils::ParseXS package variables)
for eval'ing output typemap code that may refer to these
variables.
Warns the contents of C<$@> if any.
Not all these variables are necessarily considered "public" wrt. use in
typemaps, so beware. Variables set up from the ExtUtils::ParseXS object:
  $Package $ALIAS $func_name $Full_func_name $pname
Variables set up from C<$other_hashref>:
  $var $type $ntype $subtype $arg
=cut
sub eval_output_typemap_code {
  my ($_pxs, $_code, $_other) = @_;
  my ($Package, $ALIAS, $func_name, $Full_func_name, $pname)
    = @{$_pxs}{qw(Package ALIAS func_name Full_func_name pname)};
  my ($var, $type, $ntype, $subtype, $arg)
    = @{$_other}{qw(var type ntype subtype arg)};
  my $rv = eval $_code;
  warn $@ if $@;
  return $rv;
}

=head1 TODO
Eventually, with better documentation and possible some cleanup,
this could be part of C<ExtUtils::Typemaps>.
