[131 of 159] Compiling Object.Contacts ( Object/Contacts.hs, dist/build/core/core-tmp/Object/Contacts.o )
Couldn't match expected type `Contacts'
with actual type `Maybe (Shape, CpFloat) -> Contacts'
In the return type of a call of `Contacts'
Probable cause: `Contacts' is applied to too few arguments
In the expression:
Contacts  False empty empty empty empty Nothing
In an equation for `initial':
initial = Contacts  False empty empty empty empty Nothing
aborted due to an error
With great power comes great responsibility. Pastie wisely.
