Subject: regexing a file's contents without reading the whole thing?

I see that it is possible currently to parse through a file without
reading the whole thing into RAM, a la

a = File.open('a', 'r')
a.lines{|line|
  if line =~ /some regex/
    ...
  end
}

But what if I can to do something like
a = File.read('a').scan /some regex/

is that possible?

Thanks.
