I think you mean you like emacs but got hit by autocorrect. I think the key is to duplicate a mid nineties office suit that is hackable with a programmers IDE thrown in. Something like AppleWorks or MS Works with a database that is universal across all the documents in the suite with structures that allow reuse

I think he meant Common Lisp macros, a powerful feature of the language (and missing from Smalltalk) that allows one to easily write code that writes code.

Are macros performant enough to allow a power user to replace a scripting language like elisp for a long file of strings, which if I remember correctly was the main issue with using emacs over clisp, unstructured strings.

Common Lisp macro expansion happens at compile time, so they wouldn't affect runtime performance.

...but it's a fair thing to think about if the "poweruser" interface encourages creating new macros on the fly. Common Lisp can "compile" at the REPL or otherwise in the live environment.
