hi,

thanks for your link. I saw this grammar, but
(1) I'm not sure if it's a Lua 5 grammar,
(2) it's wrong I think:

look at

primary --> NIL | number | literal | '%' name | table_cons
	 |  FUNCTION '(' [ params ] ')' block END | ( expr ) 

var     --> name
        |  primary index
        |  var index
        |  call index

according to this, it should be possible to write:

"some literal".some_key = 1

which is rejected by Lua on my system (which is Lua 5). So something isn't right here.

Thanks anyway,
klaas-jan
