This PR was merged into the 2.7 branch. Discussion ---------- Add a warning about routes parameters names limitations @wouterj @xabbuh I'm sorry guys I had to do a new branch and a new PR because I failed in the old one. I shouldn't have used the fast GitHub edit method. I fixed the indentation to 4 spaces. Also I thought this kind of information fitted more in the "advanced" area along with the special parameters than in the basic examples.
