Pseudo-event-form-list-fix

(pseudo-event-form-list-fix x) is a usual fty list fixing function.

Signature

(pseudo-event-form-list-fix x) → fty::newx

Arguments

x — Guard (pseudo-event-form-listp x).

Returns

fty::newx — Type (pseudo-event-form-listp fty::newx).

In the logic, we apply pseudo-event-form-fix to each member of the x. In the execution, none of that is actually necessary and this is just an inlined identity function.
