continuations

In this thread, you may post code that makes use of continuations, and I will attempt to produce code that does the same and looks reasonably similar, without using continuations.

False. The only mutations in the linked example implementation are in amb-collect-thunk which is not touched by amb itself. Could you stop holding down your period key too? It makes you look like a fucking idiot (though was that the intention and HIBT?)

It is quite easy to replicate the functionality of amb without continuations, but with a load of cruft as seen in your example. I want to see amb alone.
