The problem is that there is no good and efficient strategy to modify
the input ('fix' the error) so the compiler is guaranteed to be able
to continue and analyze the rest of the program in a meaningful way.
What do you do, insert a symbol, delete a symbol, ...? If the 'fix' is
wrong you're likely to end up with a cascade of error messages that
are completely missing the mark.

In the days when compiling a program took a long time there was a good
reason to pay attention to recovering from compilation errors so you
could fix multiple errors between compiler runs, but compiling a Lua
program takes milliseconds on any reasonable machine so it's probably
not worth the trouble to modify the parser to do something clever
enough to recover from most errors.
