 Replace isValid() calls with assert() 
There's more value on showing how `assert()` displays the validation
messages than simply showing if `isValid()` returns `true` or `false`.

However, that increases the chances of having outdated documentation, so
I created a doc linter that updates the Markdown files with the
correct message.
