title: How does one comment regular expressions in c++?
body: <p>Is it possible to write comments inline for regular expressions in C++?  I find the multiline commentable regexes in Python to be great for readability and maintainability later on.  Otherwise, what is the canonical way to write comments for regexes?</p>
  
  <p>Sorry, this is probably a duplicate question, but all my searching was just turning up C++ regexes to find C-style comments...</p>
