from exegesis 4:
In Perl 6, the current topic -- whatever its name and however
you make it the topic -- is always aliased to $_.
and one of the examples is:
for @list -> $next { # iterate @list, aliasing each element to
# $next (and to $_)
print if length > 10;
# same as: print $next if length $next > 10
%count{$next}++;
}
but what if there are multiple bound variables like this example:
for %phonebook.kv -> $name, $number {
print "$name: $number\n"
}
is $_ aliased to either/both/neither of the two topics? are those now
not topics but just aliased variables?
i must know the answer so i don't get drawn to the dark side of the source
