All the subs would have names in this situation but point conceded.

I'd hoped though that it would be reasonably clear that the reason for knowing the name was that I wanted to use a leading underscore to mark which handler subs should be publicised and which should not. That's the only reason - I was hoping a bit of Laziness (altering my naming convention) could save me coming up with any more elaborate means of maintaining a list of which ops should be advertised. ;-)
