<sexpbot> ⟹ "([f coll] [f val coll]); f should be a function of 2 | |
arguments. If val is not supplied, returns the result of applying f to | |
the first 2 items in coll, then applying f to that result and the 3rd | |
item, etc. If coll contains no items, f must accept no arguments as | |
well, and reduce returns the result of calling f with no arguments. If | |
coll has only 1 item, it is returned and f is not called. If val is | |
supplied, returns the result of applying f to val and the first item | |
in coll, then applying f to that result and the 2nd item, etc. If coll | |
contains no items, returns val and f is not called." |
