You may be thinking of the matrixMultiply function, which requires each array key to be a comma-separated pair of numbers. That was written before LC had multidimensional arrays; not sure if it would have been written that way if deeper arrays were available at the time.
All array keys in LC are strings. Whether a number, or a pair of numbers with some punctuation included - all just a string.
It would be nice to be able to represent deep arrays with paths, though. That's been a dream of mine for years, to be able to use XPath-like functions on LC arrays.
But alas my best efforts at simulating that in script ultimately require dynamic evaluation (do, value, etc.), where the speed loss adds up quickly since this is most worth applying to large arrays.
And given that the engine doesn't currently prohibit "/" from being part of an array key (only NULL is prohibited), I haven't bothered submitting a feature request for path syntax for arrays because I can think of no universally-applicable way to expect the engine team to do it.
