Actually, that should be (eval cmd t). Providing an alist is not

Although it does the job, it would leave an `eval' in the code base,
which is not very pretty, and more difficult to maintain (scope is less
obvious). That's why I prefer the functions. Of course, it may not be
worth the trouble if introduced backward incompatibility is really
nasty.
