- check the stack for a list argument
- if the list only has one element, return that element
- if the list is empty, STREAM generates "invalid dimension"
- otherwise do the functional equivalent to << MAX/MIN >> STREAM (whichever one was appropriate)

It's a small amount faster than the UserRPL counterpart, mostly because the executable passed to STREAM doesn't need the « » encapsulation. The total code size for all of this is 76 bytes. Is it worth including in the next update?

If so, which menu group makes the most sense? I'm thinking TEST, but LMATH might also be appropriate. I could see either for this.

Although LSORT HEAD is noticeably faster than MIN STREAM, I think LMAX/LMIN are worth including, especially if they work with strings. Also, one cannot assume that everyone has LSORT on their calculators (although I can't imagine why not).

I also concur that they should go in the LMATH menu.
