Hmmm... considering that tables are the main structure in Lua, one  
could argue that tables are for, well, everything one see fit to do  
with them...

I, for one, use FuncTable all over the place :)

E.g. using a database as an example [1]:

local DB = require( 'DB' )
local aDB = DB( 'sqlite3://localhost/test.db' )

aDB( 'drop table contact' )
aDB( 'create table contact( name varchar( 32 ), email varchar( 32 ) )' )

for aContact in aDB( 'select * from contact' ) do
    print( aContact.name, aContact.email )
end
