type.declare composition with undefined
Hello
,
I
've been playing with arktype and trying to compose validators using preexisting types with type
.declare
.
When adding undefined this falls apart during compilation
.
https://stackblitz.com/edit/vitejs-vite-cpr8tkpa?file=src%2Fmain.ts
Is there a better way to handle this
?
Thanks in advance
