some of the types (in particular, in hoisted closures) could not be reconstructed afterwards. This properly propagates the types, including to closure deconstruction time, giving additional insurance; and allowing monomorphisation not to choke on the result.

(** This module performs environment-passing style closure conversion, relying
|
|
on the existential [TClosureEnv] type and tuples for closure environments.
|
|
The implementation is based on François Pottier's
|
|
{{:http://gallium.inria.fr/~fpottier/mpri/cours04.pdf#page=10} MPRI lesson}.
|
|
After closure conversion, closure hoisting is perform and all closures end
|
|
up as toplevel definitions. *)
