Alas, Phil, one can be a plain TeX user and not agree with Don Knuth-o, 
whose offers aren't all of the "you can't refuse" type. I think @ is 
best as a punctuation mark, and spaghetti-prone as a vowel (note the 
Italian connection). And a mix with the underscore is better yet, in my 
opinion, following the pattern: \<pre>@<mac>_<sub>, where <pre> is a 
prefix unique to the package (or file), <mac> is the main macro and 
<sub> an internal sub macro. E.g.:

     \xxx at dosomething_this
     \xxx at dosomething_that
