Did some testing, / / will operate on $_ implicitly, so that's not why
it no longer works as it did.

e.g.
while gets
   print if /start/
end

will print the line containing start.

So I'm guessing that / / changed what it returns (Matchdata or nil)
compared to what it used to return prior to 1,8  (Fixnum or nil) and
that breaks using it by itself with ranges.

Of course, this is all considered bad form in Ruby now anyhow. Still,
it's very nice for command-line 1 lines ( ruby -n -e 'print if /ruby/'
input.txt )
