[julia-users] sub type definitions

[Samuel Colvin]

julia> abstract Foo

julia> type SubFoo <: Foo
       x
       end

julia> func(bar::Type{Foo}) = println(bar)
func (generic function with 1 method)

julia> f=SubFoo(1)
SubFoo(1)

julia> func(typeof(f))
ERROR: `func` has no method matching func(::Type{SubFoo})



What do I need to replace "Type{Foo}" with to get this working?

I tried "Type{T<:Foo}" and "Type{<:Foo}" but neither worked, I felt I was 
close though?
