Example in readme missing (s, t) initialization

[matbesancon]

julia> using FLoops  # exports @floop macro

julia> @floop for (x, y) in zip(1:3, 1:2:6)
           a = x + y
           b = x - y
           @reduce s += a
           @reduce t += b
       end
       (s, t)
(15, -3)

shouldn't s and t be initialized somewhere?

This example is correct. (You can check this in the REPL.)

That said, I understand that it may feel jarring for people trained to write sequential programs. It's better to clarify this in the documentation.

Indeed I had a doubt, in that case yes a mention of the special syntax working with an undefined left-hand-side of += would be great, thanks!
