I personally would prefer something like the Java annotation syntax:

@name( property1='value1', ... )

Where the '( property1='value1', ... )' bit is optional

Of course some folks might prefer the () to be {} so that this looks
like a Lua table.

So one could have single word annotations, or provide extra attributes.

As with any annotation system, if the parser doesn't recognize it,
they should be skipped.

The syntax for closeable local declarations can just use this
mechanism instead of the current proposed syntax.
