A deeper explanation of with-open
In Macro example: with-open, we developed a macro similar to the
built-in with-open. It will close input streams (and
other things with a close method) after a block of code is executed.
We actually developed two implementations. One was pure macros and the other used a helper function. @srdjan asked agreat question in the forum about it and I thought I'd answer it in video form. Thanks for the question!
