This function takes an object and returns a new set that contains all the keys from the object. Duplicate keys (for badly written object literals in Rudi code) are allowed and will simply be merged into one within the set.
(new-key-set "test")➜error(new-key-set {})➜ (empty set)(new-key-set {a 1 b 2})➜set{"a", "b"}(new-key-set {a 1 b 2 b 3})➜set{"a", "b"}
This is the only form of this function. It coalesces the given value to an object and then lists all the keys into a set. Returns an error if the given value cannot be coalesced into an object.
