I decided today that I wanted to partially apply functions in Common Lisp like you can do in Haskell.
In the package `cl-mongo`, `get-element` takes a name and a document and returns the value or nil for that element of the doc. I was messing around in the repl viewing different documents and every time I did so I had to do something like this:
Which, as an also-Haskell programmer, that is just far too verbose.
The solution was, as always, a macro.
Now I just need to figure out a better name for this. I'm sure I'll be making a lot more of this sort of thing.
