What we need is to replace the begin and end.

Lua table use { as begin and } as end.

So a possible replacement might be: (){ ... }, i.e. a table after ()
defines a function. like

(x, y){return x+y}

I do think some Macro feature can accomplish this, i.e. have some
pre-compile step for lua without actually changing lua syntax.

But we obviously should not remove the "return", since lua requires
statements in the function body instead of an expression.
