http://rondam.blogspot.com/2008/02/joy-of-iterators.html This lets you write things like: (for var in form do ... or (for var in form collect ... where form can be anything that has an iterator method defined on it. There's also a macro I use called BINDING-BLOCK (BB for short) which subsumes a bunch of binding forms. So you can write things like: (bb x (...)
y (...)
:db (q r s) (...) ; Destructuring-bind
:mv (p q) (...) ; Multiple-value-bind
...
It's extensible so you can add your own clauses. Code is here:http://www.flownet.com/ron/lisp/rg-utils.lisp (It's a little out of date. If you want the latest let me know and I'll update it.) |
