Why not the other way around.
Use their .pl-program and
use the functions inside it -
then cross-call in to your
python module:
[--- someperl.pl ---]
py_prepare
$result1 = hash_proc_1($whatever);
$result2 = hash_proc_2($whatever);
py_calculate( $result1, $result2 );
# - - - - - - - - - - - - - - - - - - #
use Inline Python => <<'END_OF_PYTHON_CODE';
def py_calculate (r1, r2):
do_something(r1 * r2)
def do_something(result):
return x - y
END_OF_PYTHON_CODE
[/--- someperl.pl ---]
This approach ensures that the
strange perl functions run clean
int their native environment.
You have access to all your py-
Modules, as in a normal python-
environment (Python globals are
directly imported, afaik).
[--- someperl.pl ---]
use Inline Python;
doit();
__END__
__Python__
from mylibrary import doit
...
...
[/--- someperl.pl ---]

I use this sometimes, it is quite nice.
