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})
println(io, "my Foo array")
end
show (generic function with 99 methods)
julia> [Foo(1,2)]
1-element Array{Foo,1}:
x ---> 1
y ---> 2
I tried this, but failed.
A workaround is to overload `display`, are there any side effects of doing
this?
