Generally speaking, no.  These languages all have quite relaxed notions of
"type" and aren't prepared to distinguish between functions on that basis. 
And since they don't do that, there is little point in distinguishing by
number of arguments either, and so they don't.  You can write a single
function and have it make decisions based on how many arguments it got
handed and what types they have, but the language won't do it for you.
