Trying to make `methodswith` work for a user-defined type.

test.jl

module Test
export TwoVals, addtwovals

type TwoVals
    val1
    val2
end

function addtwovals(v::TwoVals)
    v.val1 + v.val2
end

function addtwovals(v1::TwoVals, v2::TwoVals)
    v1.val1 + v1.val2 + v2.val1 + v2.val2
end


v1 = TwoVals(1,2)
v2 = TwoVals(100,200)

# Use functions
println(addtwovals(v1))

println(addtwovals(v1, v2))

# Discover functions
println(methods(addtwovals))

println("methodswith inside module:")
methodswith(TwoVals)
methodswith(STDOUT,TwoVals,current_module(),false)

end

println("using Test:")
using Test
methodswith(Test.TwoVals)
methodswith(TwoVals,Test)
methodswith(STDOUT,TwoVals,Test,false)
println("Inlining methodswith implementation:")
m = Test
t = TwoVals
io = STDOUT
showparents = false
for nm in names(m)
  try
    mt = eval(nm)
    d = mt.env.defs
    while !is(d,())
      if any(map(x -> x == t || (showparents && t <: x && x != Any && x != ANY && !isa(x, TypeVar)), d.sig))
        print(io, nm)
        show(io, d)
        println(io)
      end
      d = d.next
    end
    println()
  end
end
