This WILL happen if you do this:


As a silly idea, to simplify the syntax, how about:
t{ 1, 2, 3 }

Where 't' is actually a closure function wrapping up a table of your choosing?

Or t can still be a table, whose metatable has a __call method. This will call the method with a single table param. The question is what do you want to do with this. If you say:

    local a = t{1,2,3}

Then presumably you are dereferencing the table in some interesting way, and the __call function can do that for reasonable results. But this:

    t{1,2,3} = 12

is not legal Lua syntax. Unfortunately, a Lua function cannot return an 'lvalue' (in C nomemclature). Seems like it would be useful to allow a function call to be on the left side of an assignment statement. By default this:

    f(a,b) = 12+14

could translate to:

    f( {a,b}, {12+14} )

Using tables would make it easy to separate the input params from the right-side expression.

Just a thought...
