I was playing with classes and adding a closure to an attribute.
I discovered that to call a closure on object I need `.()` rather than
just `()`. See REPL below.

I was wondering whether it was intended for `()` to return something
other than `.()`?
My first thought would be that `.()` would have the same syntactic sugar
as `.[]` on an Array object.
I looked in the Documentation and in Classes found
&!callback();
inside class Task.
So I think there may be something a bit wrong. Or is this an artifact of
REPL?
