'if a then break; end'

Roberto Ierusalimschy 3cadc37f47 no more 'Proto' objects on the stack. Protos are anchored on outer 
Protos or on a Closure, which must be created before the Proto.
 2012-05-08 10:53:33 -03:00

 2011-08-23 14:24:34 -03:00
Roberto Ierusalimschy 59bcd137ae reducing even more use of C stack by the parser: struct 'FuncState'
