Just checking my understanding of the rules for writing anonymous functions ...(fn [args] ...) allows any number of expressions in its body. #(...) only allows a single expression in its body, correct? Why the difference?
Because a single expression is an important and large subset of all useful anonymous functions and typing something like:
#(* % 4)
is significantly more convenient than typing:
#((* % 4))
which would be required if #(...) supported multiple expressions.
