levels, occurring in universe instances

sort expressions

Cast to a base type (eg, an underlying inductive type)

PatCstr(p,C,l,x) = "|'C' 'l' as 'x'"

The kind of patterns that occurs in "match ... with ... end"

locs here refers to the ident's location, not whole pat

type 'a glob_constr_r =
| GRef of Names.GlobRef.t * glob_level list option

An identifier that represents a reference to an object defined either in the (global) environment or in the (local) context.

| GVar of Names.Id.t

An identifier that cannot be regarded as "GRef". Bound variables are typically represented this way.

| GEvar of existential_name * (Names.Id.t * 'a glob_constr_g) list
| GPatVar of Evar_kinds.matching_var_kind

Used for patterns only
