Vl-namefactory-maybe-initialize

Make sure that the modnamespace is computed, or generate it if it isn't available already.

Signature

(vl-namefactory-maybe-initialize factory) → new-factory

Arguments

factory — Guard (vl-namefactory-p factory).

Returns

new-factory — Type (vl-namefactory-p new-factory).

We could do this as part of vl-starting-namefactory instead, but this allows us to make vl-starting-namefactory very cheap and; avoid computing the modnamespace if it isn't used.
