Don't forget:
__tostring
I thought __tostring was a fallback... (Lua doesn't know what to do, but
instead of throwing an error it returns the memory address or a hash or
w/e)
debug.setmetatable( 1, {
__tostring = function( v ) return "X"..v.."X" end
} )
print( 1, 2, 3 )
==>
X1X X2X X3X
Or my favourite:
debug.setmetatable( "", {
__tostring = function( v ) return "bye bye" end
} )
print( "hello world" )
==>
bye bye
