Maybe the code generated should be looking something like this :
GenSym(0) =
((top(getfield))((top(getfield))(Transmission,:Download),:download_task))(Val{symbol("##7731")},x,y,v1,v2)
#s222 = (top(start))(GenSym(0))
GenSym(1) = (top(indexed_next))(GenSym(0),1,#s222)
v3 = (top(getfield))(GenSym(1),1)
#s222 = (top(getfield))(GenSym(1),2)
GenSym(2) = (top(indexed_next))(GenSym(0),2,#s222)
v4 = (top(getfield))(GenSym(2),1)
#s222 = (top(getfield))(GenSym(2),2)
I am kind of confused, can somebody offer some solution to my problem?
Thanks
