A very nice experiment using notation: we define the notation for natural

natural deduction tree! Useful to teach logic to first year students, but

the system in some way).

simplified coercDb implementation with additional info about the position of
the coerced argument. Now (C ??? x ??? y z) is printed as (x y z) when C is a
coercion and ? are implicits or saturations generated to apply the coercion to
x.
New case in unification, when there is a triangular pullback and the
coerced is not flexible an unfolding of the composed coercion is attempted.
this helps in the case:
C ??? X ??? y ? +?+ C1 ??? (C2 ??? X ???) ??? y z
where C = C1 composed C2 but X is rigid abd conversion fails cause
x != ? and the heads are different... unfolding C helps
