rawget() & metamethods

[PA <petite.abeille@...>]

Hello,

Using Lua 5.1 (work6).

I'm trying to list all the functions directly attached to a table using 
the following code snippet:

for aKey, aValue in pairs( aTable ) do
        if type( rawget( aTable, aKey ) ) == "function" then
                print( aKey )
        end
end

Works quite alright, except that this also lists all the metamethods 
defined by the table parent metatable (e.g. '__eq', '__tostring', etc) 
even though those (meta)methods are not directly defined in the table 
being enumerated.

Shouldn't rawget() _only_ return values which are effectively defined 
by a table, metatable and metamethods notwithstanding?

What gives?

TIA!

Cheers
