[julia-users] Function return type

[Ryan Li]

Hi,

As been mentioned in https://github.com/JuliaLang/julia/issues/1090, the 
return type of a function can be specified.

First of all, I found this is not available in the current released version.

Also I have another question related to this. If we can specify the return 
type of a function, could we also specify the return type of this function 
when it is used as input argument of another function? For example,

function myfun1(x::Int, y::Int)::Int
return x+y
end

function myfun2(func(::Int,::Int)::Int,x::Int,y::Int,z::Int)
return func(x,y)+z
end


Best,
Yingzhou
