But you're misunderstanding what map does: it converts its collection
arguments to _sequences_ and then it processes those sequences. Map
doesn't operate on sets, or vectors, or maps, only on sequences.
Scala goes out of its way to retain input types as output types on
many of its collection operations, and that's its choice. But it's not
how Clojure is defined - Clojure operates on abstractions above the
concrete types.
