Comment:
`perp()` isn't documented in this patch. Also,
{{{
sage: c = FreeModule(Integers(8), 2)
sage: c.perp()
---------------------------------------------------------------------------
AttributeError Traceback (most recent call
last)
AttributeError: 'FreeModule_ambient_with_category' object has no attribute
'perp'
<and later>
AttributeError: 'IntegerModRing_generic_with_category' object has no
attribute 'parent'
}}}
Apparently `Integers(8)` isn't a PID, according to Sage? This isn't bad,
but perhaps we should have a different error message... or maybe this is
okay.
