Delta implies all consts (both global (= by kernel_name) and local (= by Rel or Var)), all evars, and letin's. Rem: reduction of a Rel/Var bound to a term is Delta, but reduction of a LetIn expression is Letin reduction
Sets of reduction kinds.
fconstr is the type of frozen constr
fconstr can be accessed by using the function fterm_of and by matching on type fterm
type fterm = - | FRel of int
- | FAtom of Constr.constr(*- Metas and Sorts *)

norm_val is for strong normalization
whd_val is for weak head normalization
whd_stack performs weak head normalization in a given stack. It stops whenever a reduction is blocked.
