Hi Zelphir,

I can't help you with the processing of arguments with Guile, as I don't
know the first thing about that

I want to thank you for collecting that set of examples and tutorials

I only skimmed through the macro section and it seems quite interesting

Examples are very important and the Guile documentation sorely misses some
examples

Also, I also had the experience to struggle and waste lots of time with
Guile for quite simple things, too

For example, it too me some years to learn the usage of readline for a
better REPL experience (this information is sinked deep in the manual)

It also too me a long time to get the gist of the "eval buffer" command in
Geiser

There is another library of examples that Tantalum pointed me to, this one
https://github.com/sph-mn/sph-lib/tree/master/modules/sph/server

Together with yours, this material is becoming meaningful, if not
substantive

Maybe the Guile website could point to these collections, maybe they could
be merged into one library only, we'll see

For now I just wanted to acknowledge your effort

Thanks
