ClosLit	isa_clos_lit (Ref def, bool fn_isa_lam=true)
	Tries to match a closure literal.

std::tuple< const Extract *, N * >	ca_isa_var (Ref def)
	Checks is def is the variable of a mut of type N.
Closure Types
const Sigma *	isa_clos_type (Ref def)
	Returns def if def is a closure and nullptr otherwise.
Sigma *	clos_type (const Pi *pi)
	Creates a typed closure type from pi.
const Pi *	clos_type_to_pi (Ref ct, Ref new_env_type=nullptr)
	Convert a closure type to a Pi, where the environment type has been removed or replaced by new_env_type (if new_env_type != nullptr)
