What is __len__?

The # operator. It is not overridable for tables in Lua 5.1 (though it will be for Lua 5.2).

Btw. I smell python. Is it python inspired?

Yes.

Do you mean:

Code: Select all

#Food

???
It is possible with tables:

Code: Select all

t = {1,2,3}
a = #t
print (a)

Do you mean:

Yes.

That's not what I meant: you can't change the meaning of the # operator for tables. That changes in Lua 5.2, where #foo looks at the metatable, even if foo is a table.

Maybe this will be clearer:
