This "definition" does not reflect the reality. Actually the select() function does not just returns arg[n], it returns all arguments starting at index n up to the number of arguments in arg, i.e. it returns arg[n], arg[n+1], ... arg[#arg]

Sure it does .. Lua allows semi-colon as an alternate to comma in table constructors. From the 5.3 reference manual:

tableconstructor ::= ‘{’ [fieldlist] ‘}’
	fieldlist ::= field {fieldsep field} [fieldsep]
	field ::= ‘[’ exp ‘]’ ‘=’ exp | Name ‘=’ exp | exp
	fieldsep ::= ‘,’ | ‘;’

Note that a ‘fieldsep’ is comma or semi-colon.
