This might not be quite the question you're expecting! I don't want a regex that will match over line-breaks; instead, I want to write a long regex that, for readability, I'd like to split onto multiple lines of code.
Something like:
"bar" =~ /(foo|
bar)/ # Doesn't work!
# => nil. Would like => 0
Can it be done?

Using %r with the x option is the prefered way to do this.
