I use:

(in-package :my-package)

because uppercase is _wrong_. It's much more difficult to read, and
should be used exceedingly sparingly. IMHO (note the sparing usage...)
it was a bad mistake to specify that everything is up-cased rather than
down-cased.

For anyone interested why, it's because lower-case letters and words are
much more recognisable, whereas uppercase letters and words are less so,
since most uppercase letters are essentially squares. ISTR reading that
in some cases uppercase is semi-recognisable, but I don't recall where.

Incidentally, I know that I write 'lower-case' but also 'uppercase.'
Call it a quirk.
