Another question:
Now I know that strange whitespace comes from array's indent:
julia> [Foo(1,2), Foo(1,2)]
2-element Array{Foo,1}:
x ---> 1
y ---> 2
x ---> 1
y ---> 2
How can I define my own `show(io::IO, x::Array{Foo, 1})`?
julia> function show(io::IO, x::Array{Foo, 1})
Whenever you define an IO method, you need to make sure that all IO methods
you call within it also use that argument. Change println("x ...") to
println(io, "x …").
