Yes, it does.  But that's more verbose, and as Jozef Wagner notes, it 
creates seqs unnecessarily.

I like Jozef's solution.  However, I think a proper definition of mapc may 
have to be more complicated, in order to allow for multiple sequence 
arguments after the function argument.  Maybe as a macro that calls doseq 
in the end.

If nothing like this exists, I'd call it "map!", since "mapc" is just an 
odd legacy name from Common Lisp.  The "!" doesn't mean that map! is 
guaranteed to have side-effects, but "!" doesn't usually guarantee that, 
anyway.   (I delight in CL's idiosyncrasies, but appreciate Clojure's more 
systematic elegance.)
