Var-decl-map-fix

(var-decl-map-fix x) is an fty alist fixing function that follows the drop-keys strategy.

Signature

(var-decl-map-fix x) → fty::newx

Arguments

x — Guard (var-decl-map-p x).

Returns

fty::newx — Type (var-decl-map-p fty::newx).

Note that in the execution this is just an inline identity function.
