I don't pass such judgements.

Should an empty element in an array always be ignored silently?
Should an extra code block search for, or catch, such a thing 
before passing on to achieve the main purpose of the coding?
Presumably that might depend upon how much damage is being done.

Writing a message to warn the user of their sloppiness is quite
a reasonable action, in my opinion. This is done a lot in TeX
and LaTeX, so why not here?
