`continue` results in infinite loops

[ghost]

The following hangs:

julia> using ResumableFunctions

julia> @resumable function f()
           for i in 1:10
               i % 2 == 0 && continue
               @yield i
           end
       end
f (generic function with 1 method)

julia> collect(f())

Adding a line to print out i shows that the loop goes through once with i = 1, then repeats the loop body forever with i = 2.

Hi @cpsquonk, I have had the same issue. What I ended up doing was using an if statement instead of the continue:

@resumable function f()
    for i in 1:10
        if i % 2 != 0
            @yield i
        end
    end
end

Hi

The for iterator loop is transformed into a while loop. The update of the iterator is done just before the end keyword of the loop ... so continue skips the update and the iterator does not advance... I suppose that continue is replaced by a local jump. Something similar has to be implemented. I keep you informed of possible progress

Kind regards

Ben

I had a really productive evening;) This should work now! Feedback is welcome!
