R6RS and portability Lassi Kortela 25 Apr 2021 12:35 UTC

cond-expand isn't in the standard, but there's a very portable
implementation in chez-srfi.

The ".chezscheme.sls" trick also works but is not very convenient since
the non-portable parts have to be split at a library granularity.
cond-expand can be much finer-grained.

True.

The chez-srfi cond-expand gives reasonable results in practice, but R7RS
portability is still significantly easier.

Storing portability info in package metadata is also reasonable, but
that is even more coarse-grained than the library level thing :)

> Who tried to declare Racket as the standard Scheme implementation?

No-one declared anything; it just ended up as its own island with the
biggest community, and is now debating how many remnants of Scheme to keep.

The words "portable" and "standard" don't have universally agreed upon
meanings; e.g. some people are adamant that de facto standards are much
more important than de jure standards; other people strongly think the
opposite.

Good point.

As a practical matter, most of the existing Scheme implementations are
not geared up to achieve that kind of exact portability. It takes a lot
of work, and the value is debated. SRFIs and R7RS in general do not
strive for exact portability; a more informal design process would be
even more forgiving about exactness.

In my experience the Scheme community is exceptionally good at getting
details right, so we still tend to spend careful time on the parts where
a uniform result really matters.
