The event loop is brilliant example for how much `loop` is a full blown iteration DSL... love it or hate it ;)

I used to scoff at it at first, but after a few years of CL programming loop is one of my favourite CL constructs :)

I'm with you there. Is a bit of a mind bend, as I really disliked it the first few times I saw it.

For an even sillier mind bend, I'm using tagbody to be able to directly transcribe some of Knuth's algorithms as I am learning them.

I don't understand why turning a simple loop into a 'mindbend' is considered good. The downfall of programming is complexity, if you're getting your mind blown by a loop how are you going to do the rest of the program?

Something can be mindbending in its implementation, but offer a very convenient interface at the same time.

If mindbending isn't relating to its usage, but to its implementation, then I could see, how it could still be a good thing.

mindbending can also refer to something being deceptively simple. you might think it would be a big complicated mess, but using this one weird trick makes it really obvious what's going on.
