[julia-users] Trouble with parametric parts of a type def

[Ben Ward]

Hi, I'm tying to create a parametric type which can hold a variable which 
could be any kind of vector, and whatever the vector is, it can store one 
of the UInts. So it could have:

UInt8[1,2,3]
UInt64[1,2,3]
UnitRange(1, 3)
UnitRange(UInt16(1), UInt16(3))
... and so on.

But I'm having trouble deciding what needs to go in the parametric part of 
it's definition: e.g.

MyType{T <: (unsure of this bit)}
    val::T
end


I thought that AbstractVector{Unsigned} might be the way to go, but 
Vector{UInt8} does not inherit from AbstractVector{Unsigned}.

Thanks,
Ben.
