has no syntax ;)
yes, there are ambiguous cases of couse. e.g.
{ a = f (g)(h) }
is means:
{a = f; (g)(h);}
or:
{a = f(g)(h); }
BUT, the lua language itself has these ambiguous case, either. because in lua, "expr" is a kind of statement, and you can omit the semi-colon between statement, so if we omit the semi-colon between table element in a table constructor, we can parse the table just like to parse a lua program(only has "expr" as "statement"). so the ambiguous is not the problem -- just resolve them as lua resolve them.
the key is, can mostly people accept this semantics?

The word 'just' is one of the most terrifying words in the English
language for programmers.
yes! but we can just have a try :-)
But it would be an interesting patch...
and i will try it. it will help me to understand the parser of lua, too.
