Correct according to whom?

It could be made to work the way you expect, but that would be complicated.

: Are there other options that must be given in a particular order?

The -I option also requires a following argument, except that you can
have no intervening space if you like.  In other words, if you said

	perl -Id /usr/local/lib/perl whatever

you would add 'd' to the @INC array, and then it would try to execute
the directory /usr/local/lib/perl as a perl script, which probably won't
do anything useful.

The -D and -i switches also must be the final switch in a bundle.
