That mirrors elextr's suggestion from shortly before your post.
If you want to implement your code directly, you can use the fact that a
type block already introduces a new variable scope:
type MyType
data
otherdata
_x = Any[]
MyType(d) = new(d,_x)
end
The link you gave also gives a good example of how to define mutable data
for a class-static function.
This works well if you're type doesn't have parameters. If you want to have
method data that does depend on the type parameters, you're probably better
off going with a Dict anyways.
