[julia-users] field name aliases

[Anonymous]

Is there a way to have an alias to a field name?  For instance suppose I 
have

type Foo
x::Int
end

and I want to have Foo.y reference Foo.x, but I don't want an extra field y 
in order to save memory.  Of course why not just have

type Foo
y::Int
end

instead?  Because I wan't the user to access a field using a different name 
than the field name the programmer sees.. for reasons.
