You can. I wish I remembered the language this was in (not sure if it's in
Scala), but you can do something like:
let xml = '''
|<?xml version="1.0"?>
|<catalog>
| <...>
|</catalog>
'''
This way, if you care about the leading whitespace, you define the line
beginning using "|".
Two characters aren't harmful, but in my experience when working with HTML
strings, etc. the quote-escaping is extremely tedious.
