title: How to "alias" g++ or other commands with non-alphanumeric characters?
body: <p><code>set -x "g++" "/usr/local/gcc-7.1/bin/g++-7.1"</code></p>
  
  <p>will not work due to non-alphanumeric "++" characters.  (Error message: "set: Invalid character “+” in variable name.")  </p>
  
  <p>Am I out of luck here or is there a work around?  I just switched to fish less than 24 hours ago and not sure if there is a work around for aliasing g++.</p>
  
  <p>Thanks for your time.</p>
