PyGen - python style generators

@BenLauwens

Very Great work !

However i’am not so fond of solutions that shake the runtime at a too low level with some kind of magical macro on a general basis.

So i have handcoded my yield

struct PSerie
    p
end

function Base.iterate(ps::PSerie, itr=(0,1,0))
    s,n,y = itr
    if y == 1; @goto y1 end

    while true
        s += 1.0/(n^ps.p)
        return s,(s,n,1)
        @label y1
        n += 1
    end
end

And you can too

Creating Generators

Suppose you have this in python # aka riemann serie def p_serie(p): assert(p>0) s = 0 n = 1 while True: s += 1.0/pow(n,p) yield s n += 1 then run itr = p_serie(2) [next(itr) for _ in range(10)] that output (reformatted) [ 1.0, 1.25, 1.3611111111111112, 1.4236111111111112, 1.4636111111111112, 1.4913888888888889, 1.511797052154195, 1.527422052154195, 1.5397677311665408, 1.5497677311665408 ] (1/2)
