The first time I saw the "!" syntax, it was slightly confusing to me
in that it's similar to various shells using "!" for history expansion
-- especially given that these things are popular with shell aliases
made it hard to remember.

An alternative character that wouldn't have confused me, and even
suggests shell commands is ";".  So my preference would be for shell
aliases to start with it and to be invoked in the original working
directory, perhaps deprecating the "!" syntax.

But I'm new enough to be safely ignored...  So this is all a
parenthetical comment...
