I don't think I meant that. I think it still should accept variables
as well, so it would still be ambiguous as to whether it referred to
the value of the property Fot of object $obj, or the method Fot on the
$obj class.

Also, just in general using something that has the same syntax as
current PHP code, but a different meaning, sounds like a bad idea.

That has the downside of exposing the implementation detail, that it's
implemented through closures, which would be a regrettable choice if
we ever decided to change the implementation details in the future.

And it also has the downside of looking like a function call, but
having different rules for what can be put inside it:

function foo();
closure(foo); // fine.
special_closure(foo); // syntax error, undefined constant foo.

 Although avoiding new syntax is good in general, if what can go
inside it is different, then I think it requires a new syntax.
