Hello,
I would like to change the expansion of a given module.
I tested:

p.s. I didn't mean my reply to disregard what Matthias showed. In

of wrapping just that in a form that's a bit more convenient on the
provider side, and if necessary cooperates automatically on the
require/typed side??

That's precisely the behavior you want:
-- what's exported is the public name, which would usually check/do things
before it calls private
-- while the unprotected private one is not provided and should not be
visilble.
How does the mechanics work? Well it delivers path names to these priv
In this example, why can syntax produced via macro reach the private function,

program gives this error: "if: expected a question and two answers, but

This is my program.

If it can be of any help: here at Middlesex University we managed to compile
the standard sources for 5.93 on a Raspberry Pi (standard raspbian distro). The
only thing we had to do was to disable documentation in the configuration step
(configure --disable-docs). And then wait a few hours.
