If I have a statement like:

        somedata.foo(arg1,arg2)

now,what is the type of somedata? a table or a userdata?

according to the reference manual in

2.3 - Variables

"The syntax var.NAME is >>just<< syntactic sugar for var["NAME"]:

        var ::= prefixexp '.' Name"

"Square brackets are used to index a table:

        var ::= prefixexp '[' exp ']'

The first expression (prefixexp)  >>should<<  result in a >>table<< value;"

Now,according to the reference manual,the somedata is a table.
But really it is a userdata. Is there something Wrong?



might be a metatable to an userdata. kindly check the section on
metatables
