KIP-0029: Proposal of new guard type: Constant boolean guard

[CryptoPascal31]

The idea is to propose a new guard, the most simple as possible, the easiest to understand.

But it's currently missing, and would be very useful, and would improve the clarity.
Nothing revolutionary.

This seems extremely useful, I assume it would help with things like the function below. You can type specify bool, arrays, objects, strings, but not guards that I am aware of. So we end up having to add extra helper functions which serve no real purpose.
(defcap USERPAY (account:string)
(with-default-read taxes account {'guard: (create-null-guard) } {'guard:=guard}
(if (!= guard (create-null-guard))
(enforce-guard (at 'guard (coin.details account)))
(enforce-guard guard)
)
)
)

(defun enforce-null:bool
()
false)

(defun create-null-guard:guard
()
(create-user-guard (enforce-null)))
