[julia-users] module/function/type scope confusion

[Dustin Lee]

Given two files:

SomeLibrary.jl
===============
module SomeLibrary

export MyType, foo, bar

abstract MyType

function bar(mt::MyType)
    println("I'm in MyType/bar")
    mt.x * 3
end

function foo(mt::MyType)
    bar(mt) + 1
end

end


main_program.jl
===============

using SomeLibrary

type NewType <: MyType
    x
end

function bar(nt::NewType)
    println("I'm in NewType/bar")
    nt.x * 2
end

println(foo(NewType(10)))




When running main_program.jl  I'd expect:

I'm in NewType/bar

But instead I get

I'm in MyType/bar

So I guess my expectations are a little messed up.  I'm hoping someone can 
help me think through the logic of scoping here.

Why isn't the more specific type function being used?

I'm on Julia 0.3.

thanks
