If you want both methods and attribute-like access to userdata, you
have to explicitly distinguish between the two in your userdata
design.  __index for userdata typically returns a function, but if in
your __index method, you detect that the key being accessed is
actually an attribute, you can instead call that function and return
its result.  In my userdata, I keep separate tables of settable and
gettable attributes and check these in __index/__newindex to get
attribute-like access.
