Re^2: A pair of "mathematical" attributes for arrays?

[moritz]

Obviously a while (@bar) would run until all memory was exhausted

Why should it? An empty array with non-zero default values would still be false, right?

Oops. I somehow convinced myself that while works for array iteration something like it does with a filehandle.

Array iterators (each, foreach, etc) should only deal with existing indexes. An empty array should be false.
