I'm looking for a way to "subtype" Lua files, for file objects to hold additional attributes. It seems I cannot directly set attributes on Lua Files, since they are userdata. Is there a way to write a custom file type that delegates file methods to an actual Lua file (open in mode 'r')? My trials using __index with a table or function launch errors like:

lua: _essai.lua:44: calling 'read' on bad self (FILE* expected, got table)
stack traceback:
	[C]: in function 'read'
	_essai.lua:44: in main chunk
	[C]: ?

How should I write __index to call a method on a *FILE?
