Errors will be thrown when a key is not aligned, when

If an error is found in one of the above areas, then errors
are not reported for the rest of the line to avoid reporting
spaces and columns incorrectly. Often fixing the first
problem will fix the other 2 anyway.
For example:

In this array, the double arrow is indented too far, but this
will also cause an error in the value's alignment. If the arrow were
