1. The documentation that says that the parameters need to be
convertible to immutable is outdated. This was changed a while ago to

Good to know. Yet, I wonder why such changes are not discussed on this
NG and at the very least announced in the change log...
Just download the documentation of two subsequent versions and run gnu
diff. It's that simple.
It's not in the docs. I don't remember ever hearing about this, and I
can't find this documented anywhere. And I made the patches for all of
the improvements to the compiler's support for pure which have happened
in the last year.
There have always been bugs where the compiler accepts 'const' instead
of immutable. These date back to 2.022, when pure was first implemented.
In fact, my motivation in bringing up this topic was after I observed
these bugs, and realized that most existing 'pure' code will break when
they are fixed. Also 'pure' will become even more useless than it is now.
