[ any->ascopydeep ]
The [any->asCopyDeep] method returns a deep copy of an object. In general, the [any->asCopy] method is sufficient, but in the rare circumstance when an isolated, exact copy is needed, the [any->asCopyDeep] method provides jus that.
In Lasso, a type has depth if it contains other objects, so the [integer] and [string] types, for example, have no depth. This means that [any->asCopy] is the same as [any->asCopyDeep] for these types. Other types, such as the [array] type, do contain other objects and therefore have depth. To read more about shallow copying and its effect on types that have depth, please see the [any->asCopy] method description.

Demonstrating a deep copy
The code below demonstrates what happens with a deep copy. The result will show that the copied array's elements are different than the original's.
Code
local(original) = array('radish', 'carrot', 'cucumber', 'olive')
local(copy) = #original->asCopyDeep
iterate(#original) => {
loop_value->uppercase
}
#original
'<br>'
#copyResult
array(RADISH, CARROT, CUCUMBER, OLIVE) array(radish, carrot, cucumber, olive)
