The problem with "smart" shells is, as someone had pointed out already, they tend to be a little too smart:
$ rm *.o #let's remove any object files that may exist. This command should do nothing if there are no matching files...

Of course this is much less an issue if it asks what you meant instead of assuming, but it can still be annoying. (and you'd be surprised how many "smart" tools don't ask...)

What I'd find more useful than a smart shell is smart tab completion. E.g. I might start typing "SELECT " and hit tab, and have that turned into something like [[psql "SELECT "]], with the cursor keeping its position, and then further tab presses listing available databases and columns much like existing shells' tab complete lists directories.

Of course there's a good reason this doesn't exist (that I know of): it's difficult to do, and even more difficult to do well.
