Whereas fallbacks had a global nature, tag methods + work on objects having the same tag (e.g., groups of tables). + Existing code that uses fallbacks should work without change. + + new, general syntax for constructors {[exp] = exp, ... }. + + support for handling variable number of arguments in functions (varargs). + + support for conditional compilation ($if ... $else ... $end). + + cleaner semantics in API simplifies host code. + + better support for writing libraries (auxlib.h). + + better type checking and error messages in the standard library. + + luac can now also undump. * Changes since version 2.4 + io and string libraries are now based on pattern matching; |
