Do other languages apart from Erlang have the ability to send code to running instances?

Question

I just learnt that Erlang can remote load code and modules onto all instances of a cluster by using the "nl" command. Can any other languages do this?

Answer 1

Technically any of the lisp dialects could do it. Since 'code is data' in lisp, passing some code onto a different box and 'eval'-ing it would do the job. SLIME does this to some extent via remote repl using sockets.
