# A simple propositional test
(~r → p) & (r → q) -> (p | q)

# The Application axiom should derive instantly in both j0-new and j0-ghari
x:A → y:(A → B) -> y*x:B

# ... and this one should fail instantly
x:A → y:(A → B) -> x*y:B

# This is a good one: it works in both j0-new and j0-ghari, but inspects about 
# 18000 formulas in the latter (or 8000 if x:A is in the CS instead of the
# antecedent)
x:A → y:(A → B) → y*(x+x'):B

# ... And this one just gets too complex to find at all
x:A → y:(A → B) → (y+y')*x:B
