Check-branch

Check if a branch is statically well-formed.

Signature

(check-branch branch ctxt) → result

Arguments

branch — Guard (branchp branch).

ctxt — Guard (contextp ctxt).

Returns

result — Type (type-resultp result).

We check that the condition is a boolean. Then we augment the context with the condition and we check the action, whose type is the type of branch.
