Overview

Minor readability improvement

Before

response_code is a bit opaque

After

$this->isSuccess()

Technical Details

This just adds isSuccess as a function to avoid having to understand what
response code is.

I grepped & didn't find 'response_code' outside the class/test

I also confirmed that the retrieve function casts to an int (via
validate) so the triple = is correct

Comments

This facilitates some more cleanup
