Re: small samples: macros?

One thing that occurred to me when looking at your
recent samples is that "good" TeX authors define macros
for things like vectors, so they have

\def\Vector#1{{\bf #1}}

or whatever, so that they can adjust the formatting at any time
for all vectors. We use something similar in an an internal
project and add some type information as well. While I know
you were asking about the final, expanded expressions, what
are the plans to allow macros?
