What might this be good for ?
For implementing recursion in a lambda function.
Writing in functional style, one creates many functions, and
looking for reasonable names for these functions becomes
unnecessarily painful.
May I suggest the "recur" or "recursive" keyword?
auto factorials = map!(n => n ? n * recur(n-1) : 1)([1, 2,
3]).array;
assert(factorials == [1, 2, 6]);
