Subject: Robust flatten for collection?

Hi there

A question to test your sagacity :)

I'm looking for a method which would flatten a collection, regardless of whether the collection is already flat or not.


that is:
#((1 2 3) (4 5 6)) flatten  --> #(1 2 3 4 5 6)

#(1 2 3 4 5 6) flatten  --> #(1 2 3 4 5 6)

#((1 2 3) 4 5 6) flatten  --> #(1 2 3 4 5 6)


Any idea about the best implementation for this?
