Problems with mako.strict_undefined

[magical]

With mako.strict_undefined enabled, location pages throw the following error:

NameError: 'cond' is not defined

It seems like mako is getting confused by the list comprehension on this line:

spline-pokedex/splinext/pokedex/templates/pokedex/location.mako

Line 84 in f053eb9

condition_encounters, lambda k: [len(k)] + [cond.id for cond in k]):

This is really an issue with mako, not spline-pokedex, but i'm filing it here so i don't forget.
