In my opinion, it is generally a bad idea to support different syntax
based on an INI setting. This easily leads to confusion for those
reading the code.
I don't see much point in these "simplifications" anyway, except maybe
for the shorter array literals. Note though, that there has been RFC[1]
about a similar syntax, but that had been declined.
