When would you store or pass around the intermediate callback (the 
result of reduce($initial)) without immediately invoking it with a 
callback? If you just run "reduce($initial)($my_fn)($data)", it seems no 
more useful than "reduce(42, $my_fn, $data)", which would be more 
efficient internally.

If anything, I can imagine wanting to write $my_reduce = reduce($my_fn) 
and then $my_reduce($initial, $data), but that's still 2 steps rather 
than 3.

Genuine question, not a criticism - this functional(?) style of 
composition is not something I'm very familiar with. (For the same 
reason, I struggle to read that function definition no matter which 
syntax it's expressed in.)
