Iterate a unary

 v1 each x   each[v1;x]       v1 peach x   peach[v1;x]
(vv)each x   each[vv;x]      (vv)peach x   peach[vv;x]

Where

• v1 is a unary applicable value
• vv is a variadic applicable value

applies v1 or vv as a unary to each item of x and returns a result of the same length.

That is, the projections each[v1;], each[vv;], each[v1;], and peach[vv;] are uniform functions.

q)count each ("the";"quick";" brown";"fox")
3 5 5 3
q)(+\)peach(2 3 4;(5 6;7 8);9 10 11 12)
2 5 9
(5 6;12 14)
9 19 30 42

each and peach perform the same computation and return the same result. peach will divide the work between available secondary tasks.

each is a wrapper for the Each iterator. peach is a wrapper for the Each Parallel iterator. It is good q style to use each and peach for unary values.
