val evar_absorb_arguments : Environ.env -> Evd.evar_map -> EConstr.existential -> EConstr.constr list -> Evd.evar_map * EConstr.existential

Instantiate an evar by as many lambda's as needed so that its arguments are moved to the evar substitution (i.e. turn ?x[vars1:=args1] args into ?y[vars1:=args1,vars:=args] with vars1 |- ?x:=\vars.?y[vars1:=vars1,vars:=vars]

val split_as_array : Environ.env -> Evd.evar_map -> type_constraint -> Evd.evar_map * type_constraint

If the constraint can be made to look like array A return A, otherwise return None (this makes later coercion possible).

val presplit : Environ.env -> Evd.evar_map -> EConstr.t -> Evd.evar_map * EConstr.t

Used for bidi heuristic when typing lambdas. Transforms an applied evar to an evar with bigger context (ie ?X e to ?X'@y=e).
