@flatten(t:tab)
@flatten(t:tab, n:numeric)
flatten(t) returns a new tab where where the nesting structure of
t has been flattened. For example,
@flatten([[1, 2], [3], [[], [4, 5]]]) -> [1, 2, 3, 4, 5]
flatten(t, n) returns a new tab where the first n levels of nesting
have been flattened. If n == 0, the function is the identity. If n
is strictly negative, it is equivalent to without the level argument.
@flatten([1, [2, [3, 3], 2], [[[4, 4, 4]]]], 0) -> [1, [2, [3, 3], 2], [[[4, 4, 4]]]]
@flatten([1, [2, [3, 3], 2], [[[4, 4, 4]]]], 1) -> [1, 2, [3, 3], 2, [[4, 4, 4]]]
@flatten([1, [2, [3, 3], 2], [[[4, 4, 4]]]], 2) -> [1, 2, 3, 3, 2, [4, 4, 4]]
@flatten([1, [2, [3, 3], 2], [[[4, 4, 4]]]], 3) -> [1, 2, 3, 3, 2, 4, 4, 4]
@flatten([1, [2, [3, 3], 2], [[[4, 4, 4]]]], 4) -> [1, 2, 3, 3, 2, 4, 4, 4]
@flatten([1, [2, [3, 3], 2], [[[4, 4, 4]]]], -1) -> [1, 2, 3, 3, 2, 4, 4, 4]
