So... hrmmm... this is doable, sort of.

The parser translates `- expr` into `0 - expr`, so I could watch for the binary 
subtraction op where the lhs is int(0), but that feels like it'll lead to a weird 
inconsistency where actual `0 - expr` yields a call to __minus(), but `1 - expr` 
doesn't have any overloaded meaning.

I'm going to put my implementation of this on the shelf for now and give it some 
thought...

The operator PECL package have not had a release for 4 years and development activity seems to have ceased, if a new maintainer picks up this package, then this report should be re-opened
