This? 
elsif( @ips ? $sel->count >= $max : $sel->count )

What you call educative I call overly clever and in this case outright obstructive. This is the equivalent when you get rid of the ternary 
elsif( ( @ips && $sel->count >= $max ) || $sel->count )

[download]
Which is clearer and not even longer. And once you see it like this and realize @ips is not used in within the following block, it becomes apparent you can safely omit that and the conditional becomes 
elsif( $sel->count )

[download]
One should keep conditionals as simple as possible. Similarly is this 
my @connects;
for my $fh ( @connects = $sel->can_write($timeout) )

[download]
suboptimal. Apart from, again, obstructing the conditional, one should keep declaration and initialization as close to one another as possible. 
my @connects = $sel->can_write($timeout);
for my $fh ( @connects )

[download]
This is better.
