Hello: I've created a patch for this. The only difference is that instead of flattening to a particular depth, it flattens by a particular number of levels. I thought this was more in the spirit of FLATTEN. If we want to flatten to a particular depth, it is a trivial computation. I've attached a patch for the function, as well as tests.

Hi,
I've found it useful to be able to specify a depth when flattening a list structure. The attached patch adds a :to-depth keyword parameter to the flatten function. For instance,
(flatten '((a b) (c (d)) :to-depth 1) => (a b c (d))
Is this something that could be added?
Possibly. Please explain it in the docstring and send the patch as generated by git format-patch.
Cheers,
