i've often wanted something similar, but i'm not sure you can
re-use ^ and $, as for example ,x/;$/d would stop working.

i thought perhaps « and » would do the job, but that's
not considered a good idea.

here are some relevant articles from the archives:

    http://9fans.net/archive/2003/10/340
    http://9fans.net/archive/2003/10/341
    http://9fans.net/archive/2003/10/343

basically, it might be useful, but there's no way to fit it into the syntax.
