That's no longer supported as of 1.8, but unfortunately gives no
error, according to page 64 of PickAxe2.

while line = gets
    puts line if line =~ /start/ .. line =~ /end/
end
 
is the correct form now. 

Note: gets and print still operate magically on $_ in 1.8.2 but I'm
guessing  /  / doesn't, and hence that example no longer working.

More in line with the original example, I'd guess that this also works:

while gets
    print if $_ =~ /start/ .. $_ =~ /end/
end
# $_ implicit for gets and print
