Subject: Can someone explain this regex issue to me?

Using 1.9.3p194:

> puts "\+"
+

> puts "\\+"
\+

> puts "\\"
\

However not what I'd expect (1):

> puts "hi + bye".gsub(/\+/, "\\+")
hi  bye

This gives the expected output:

> puts "hi + bye".gsub(/\+/, "\\\\+")
hi \+ bye

I can understand why I need to double escape the + to get \+ in the
output but shouldn't (1) above at least print "hi + bye"?
