Apl can be read as english as well, and frequently also obviates nesting (lisp revels in it, but humans don't deal well with deeply nested structures). Your example: 0.5*⍨+/×⍨3 4. That is, the 0.5 power of the sum of the squares of the legs. But notice: uniform precedence (like lisp) and no nesting whatsoever. (√ as sqrt is not generally primitive, though it can be trivially implemented.)
