in reply to no warnings 'recursion' does nothing?

Not withstanding your "working as expected", before I would consider silencing this warning, I'd want to be very sure that this data structure that I'm cloning that goes more than 100 levels deep is actually correct.

Personally, I find it very hard to imagine a use for such a deeply nested construction. Shared or otherwise.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

In the absence of evidence, opinion is indistinguishable from prejudice.
