The "classic" prog still exists in Common Lisp. You probably haven't heard of it because it's almost never used. Here is the description in the HyperSpec: http://clhs.lisp.se/Body/m_prog_.htm#prog In Common Lisp terms, it's a combination of LET, BLOCK, and TAGBODY.
There's also progv which, off the top of my head, is the only thing in the CL standard that lets you establish bindings (dynamic only for obvious reasons) on a non-constant list of symbols.
