Multiply defined error for instances of types imported qualifiedly
It seems to be impossible to instantiate a class for two types that are imported qualifiedly. The following causes a "multiply defined" error on the current stable/itask compiler:
module inst
class c a :: a
instance c 'inst_a'.A where c = 'inst_a'.A
instance c 'inst_a'.B where c = 'inst_a'.B
definition module inst_a
:: A = A
:: B = B
