Do you have an example of a macro that can't be replaced by higher-order functions and laziness?

I believe I do: one macro I found useful when writing a web app in Lisp was something I called hash-bind, which binds variables to the values in a hashtable, with the variable names as keys. For example:

I have one for binding GET/POST variables to regular variables transparently and with error checking, just inside the body of the macro. -- -alex http://www.ventonegro.org/
