You could also simplify the closure since @tasks is in the closure's
lexical scope, eg,
my $report_static = sub { print $tasks[$iter++]; ... };
foreach $task (@tasks) {
if (...)
$report_statics->();
else
$report_dynamic->();
...
}
But with everything in lexical scope, you could just pass any needed
arg's directly and
eliminate the closure altogether.
