The perl ref object is a python object that encapsulates a perl reference. This example shows references to an array and a function:

>>> import perl
>>> inc = perl.get_ref("@INC")
>>> inc
<perl ARRAY(0x80db158) ref at 80ecd58>
>>> len(inc)
6
>>> add1 = perl.eval("sub { $_[0] + 1 }")
>>> add1
<perl CODE(0x812c57c) ref at 80f5dd0>
>>> add1(2)
3.0
>>>
