 Review comment:
   I'll change it because I don't really care that much - though for my money 
"url" is nonsense that doesn't mean anything while "URL" stands for something - 
but I don't think it's fair to require a convention not agreed-upon by or 
enforced mechanically by the project. If local variables should start with a 
lowercase letters, there should be a linter configuration introduced to the 
repository and approved on the mailing list.
