That part was referring to regexps used in a language grammar. The  
way the language parser works is by matching the patterns line-by-line.

Not to forget (?x) which enables extended mode, where whitespace is  
ignored, and comments can be written simply with #. So we can do

     [A-Z]+    # first match one or more capitals
     \s+       # then match mandatory whitespace
