•Re: Getting name of sub from a hash-based dispatch table?

Why do you need to know "the name"? It might have many names, and it might not even have a name, as in:

my %ops = (
  '+' => sub { $_[0] + $_[1] },
  '-' => sub { $_[0] - $_[1] },
  '*' => sub { $_[0] * $_[1] },
);

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. ;-) [Jon]	[reply]
