Re^7: Keeping a Count in foreach

Your use of

($. || 1 .. undef) -1

totally baffles me. This must be an obscure effect. I read this as a scalar use of the range operator with start and stop conditions but you say that it's in list context instead.

I can reduce this to:

((undef or 1) .. undef) - 1

but no more.

Can you shed more light on what anonymous variable is keeping count?

Can you shed more light on what anonymous variable is keeping count? The flip-flop range operator remembers its state, so in a way, each flip-flop has it's own anonymous variable. And it is in scalar context.	[reply]
