So the length of {1,2,beta=3} is 2; {alice=1,bob=2} has length 0.

Generally to count all elements of a table, you need to do a foreach
or pairs loop.

Is the foreach still available? I don't see it in the table library
documentation. Sorry for such a simple question, but I like the idea of
using foreach, but only if it is going to be in Lua for many versions
to come. Thanks.
