data_ctor("Red", "Traffic").
data_ctor("Green", "Traffic").

defined_in("Zoink", "Fnord").
defined_in("Traffic", "Test1").
defined_in("Sum", "Test1").

% rules
defined_in_star(X, Y) :- defined_in(X, Y).
defined_in_star(X, Y) :- defined_in(X, Z), defined_in_star(Z, Y).Using psc-query, these can be obtained from PureScript source code:
module Fnord.Zoink.Test1 where
data Traffic = Red | Green
newtype Sum a = Sum a
f x = x + 1
