I'm afraid this, while appealing, in my testing generates an
incorrect result, ie, 1.
<SPECULATION>
What happens I suspect is that the map{ } is in void context, not the
scalar context of the outer do{}. Remember parsers are not as
all-knowing as we'd like them to be. Therefore map churns merrily
along and tosses its intermediate results until the final line.
Only at that point does parser wake up and say "Aha, the do{ } wants
scalar context so my final map{} value needs
to be returned in scalar context. So here's what map{} does in
scalar context. From 'perldoc -f map' :
In scalar context,
returns the total number of elements so generated. Evaluates
BLOCK or EXPR in list context, so each element of LIST may
produce zero, one, or more elements in the returned value.
^^^^
Remember, map has tossed all but the final value at this point so it
just returns 1.
Clear as mud?
