This text changed in CL 139099 to add "explicit" in front of "conversion".
But now "explicit conversion or assignment" reads like it might mean
"explicit [conversion or assignment]" when what is meant is
"[explicit conversion] or assignment". To make clear that explicit does
not apply to assignment, use "assignment or explicit conversion".

Adjusted spec to explicitly define the string length as the
number of bytes of the string; the prose now matches the prose
for arrays. Made analogous change for slices.

In ARM64 ABI, R18 is the "platform register", the use of which is
OS specific. The OS could choose to reserve this register. In
practice, it seems fine to use R18 on Linux but not on darwin (iOS).
Rename R18 to R18_PLATFORM to prevent accidental use. There is no
R18 usage within the standard library (besides tests, which are
updated).

A prior attempt at addressing the issue got bogged down in an
endless conversation around the subtleties of Read semantics.
Let's not go there.
Instead, we put the issue to bed, perhaps not in perfect comfort
but well enough, by moving a line of the example so that even
if there is a "benign" error as the issue suggests, the loop
terminates with n and err correctly set.

The spec currently provides a syntactic rule for receiver base types,
and a strict reading of those rules prohibits the use of type aliases
referring to pointer types as receiver types.
This strict interpretation breaks an assumed rule for aliases, which
is that a type literal can always be replaced by an alias denoting
that literal.
Furthermore, cmd/compile always accepted this new formulation of the
receiver type rules and so this change will simply validate what has
been implemented all along.
Fixes#27995.

I've linked the gophers discord. It's a well administered discord which already got many members, but it was never officially linked. For many people it's a quality proof if a discord is linked on the official page. I think there are much more people out there, who would prefer to use discord instead of slack or irc.
The discord already got many users without even being promoted, so it's very likely there are many people who are interested in a discord, but they don't want to use unofficial discords. This discord shouldn't be seen as a competitor for the slack, it's a platform for those, who don't want to use slack.

The spec used the term "conversion" somewhat indiscriminately for
explicit conversions that appear literally in the source, and implicit
conversions that are implied by the context of an expression.
Be clearer about it by defining the terms.
Also, state that integer to string conversions of the form string(x)
are never implicit. This clarifies situations where implicit conversions
might require an integer to change to a string (but don't and never have
done so). See line 3948.
