Actually, this is just a copy of the 'vac' macro from json-abnf; I changed
the name because I had no idea what 'vac' means - whereas 'mrp' stands for
'mutually recursive parser'.
just a nit-pick: You also need this kind of thing for self

Ironically, that is exactly what the SRFI-27 module implements.

Could make an insecure random source, or even a totally non-random random
source I imagine.
I had no idea it was so comprehensively extended.

If this is such an important feature it may make more sense to include
a proper PRNG.
Different applications will want fast crude random-ish numbers, PRNGs,
cryptographic PRNGs, or full quantum

I also saw that comparse provides a similar macro called
'recursive-parser', but for some reason that didn't work when I tried it.
Maybe I was using it wrong.
That's right -- it's slightly

Thank you Michele! This is a nice example.
Nice but maybe not very useful:
(apply-syntax or (#f (+ 1 2) (print hello)))
is just a longer and more cumbersome version of
(or (#f (+ 1 2) (print hello)))
A far more
Thank you for more examples!
I want to learn some basic macro programming in Chicken. However, it seems
there are multiple macro definition APIs in Chicken: define-syntax,
syntax-rules, syntax-case, define-macro. Which one should I start with?
Also, I have heard that, different from Lisp, macro

Define-macro is completely obsolete and not supported
