Re^4: do $n exist in grep?

It's also possible to shorten the lines with

('--somearg'  => $somearg ) x !! $somearg,
('--otherarg' => $otherarg) x !! $otherarg,
[download]

but only if the left hand side of x doesn't have any side-effects (because unlike the ternary operator, foo() x 0 still calls foo).

map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]

That's interesting. I'm not sure it qualifies as coding for clarity, but perhaps neither does my example. Dave	[reply]
