Now the generated code looks like this:
AST(:($(Expr(:lambda, Any[:x,:y],
Any[Any[Any[:x,:Any,1],Any[:y,:Any,1],Any[:v1,:Any,7],Any[:v2,:Any,7]],Any[],0,Any[]],
:(begin # none, line 2:
NewvarNode(:v1)
NewvarNode(:v2)
v1 = 2.1
v2 = 2.2
(v1,v2) =
((top(getfield))((top(getfield))(Transmission,:Download),:download_task))(Val{symbol("##7731")},x,y,v1,v2)
return v1 + v2
end)))))
however, when i call test(1.1,2.2), it gives me the following error:
