Which has always been true, but for my own edification... Some bloggers
used to say the old 2.x parser was more easily confused by one form than
the other. I presume that is all fixed in 3.x, and does it even/still
hold for 2.x? (We have policies with both, depending who wrote 'em.)
I would just say... pick one and stick to it (shove it in your local
site's style guide or something).
