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.
Recursive lambdas? o.O
Instead of changing the language, I'd say your situation merits
using the Y combinator... maybe define Y(f) to be (g => g(g))(g
=> f(x => g(g)(x)))
then if you need to define factorial, just say...
fact = Y(fact => n => n > 0 ? n * fact(n - 1) : 1);
