I hope you're not serious that $# would make a good operator. Apart from
conflicting with the comment marker, it is u-g-l-y.
That's the problem with operators... all the good ones are taken.

I think they would.
You seem to have missed the context of the thread. The Original Poster
was complaining that len() should be a method, because that is more
purely Object Oriented.
If len() were an operator, that too would be a compromise to the ideal of
"every function is an object method". I'm sure there are OO fan[atic]s
who dislike operators too.
