No, not for terseness. Numpy is nice because it extends Python in a reasonably good and efficient way but standalone it doesn't do much of anything and Python is so much more verbose than APL. That's the beauty of APL in a way: there really is nothing left to remove.
You can't define operator precedence though!! (That's a good thing). There was once a Julia talk about a really old programming language which disallowed any operator groupings without parens except for the basic seven or eight.
