I avoided it so that the post does not become very long and the main point doesn't get diluted. That said, I do use multiple-promise-depenencies to implement PCL:LET in the accompanying source https://github.com/chaitan

While tel:// URLs open the Phone app without any prompt, there's also a telprompt:// scheme which opens the Phone app with a prompt. As an app developer, would you ever want to use the latter scheme instead of the f

For those wondering about reader macros in Common Lisp, I wrote a tutorial a couple of months back that allows the Lisp reader to understand JSON: https://gist.github.com/chaitanyagupta/9324402
