misc-extensions

This project is intended as a catchall for small, general-purpose extensions to Common Lisp, typically macros. It is in the public domain.

Current contents:

New-Let, a macro that combines and generalizes let, let*, and multiple-value-bind. Very handy for those who make heavy use of multiple values, as I do.
GMap, yet another iteration macro, that generalizes map (hence the name). Taste in iteration macros varies widely — personally, I despise loop, considering it a conspiracy to make Lisp look like Cobol. GMap is much more elegant, in my eyes. GMap is quite reminiscent of Series, but much simpler and ultimately less powerful; yet it handles a lot of common cases, and seems to me (its author) very easy to understand and use.

More information can be found on the CLiki page.

I invite others to submit for inclusion macros or other extensions they think might be of general interest. The only requirements are

The code should be small; if it's bigger than 1000 lines or so it probably deserves its own project.
You should have been using it yourself already, for long enough that you expect it to be quite stable.
It should be something that could be useful in any Common Lisp program.
Loading the source or object file must not, per se, modify the behavior of Lisp; no redefining builtins or modifying the standard readtable until the user takes explicit steps (e.g. use-package, shadowing-import) to activate the functionality.
Don't break asdf-installability.
And, of course, you must be willing to release it into the public domain.

Documentation is in the source.

I expect the volume on these lists to be extremely low.
