Island detection while creating surfaces from curves

Packages
1

I’m thinking about creating flat surfaces with holes in them from a given set of curves. Basically I would need to detect ‘islands’ in a list of curves. Once I have isolated the islands I could create a separate geometry and intersect the surrounding surface to get the hole.

Am I overthinking this? Anyone beat me to it?

Thanks Paul, looks promising.
