func NumberValuesMergeSum[K comparable, V constraints.Float | constraints.Integer](m ...map[K]V) map[K]V

func StringKeys 

func StringKeys[V any](m map[string]V, xf func(s string) string) []string

StringKeys takes a map where the keys are strings and reurns a slice of key names. An optional transform function, `xf`, can be supplied along with an option to sort the results. If both transform and sort are requested, the sort is performed on the transformed strings.
