At first read your message seems on topic and reasonable.

But I keep thinking - THIS ADDS NO VALUE.

Hence my reply.

In that,

1) no-one has any good idea *how* to write a viable macro-language/source
2) Saying "this would be a good use case for it" is true, but pointless if
   we don't have one, or any route to one
3) repeatedly mentioning something as a "nice to have" doesn't change this.

Hence your reply is not useful, because it does not advance this discussion.
Or any discussion.

It doesn't add any value to this to say "This hypothetical other technology
that doesn't exist is a viable alternative to something we do have"

I'm asking you (and everyone, really) to stop mentioning concepts that don't
have any viable implementation. If we're proposing feature A, please stick
to insightful comments/observations for approaches that we can deliver it
using the technology that we have, rather than proposing feature B as a
prerequisite and hence a blocker.

(If you have some idea how to implement feature B, that's cool, but it
ought to be on a new thread.)

And as Neil and others have written previously, sending "harmless" mails is
not harmless - there is a cost to everyone else to read (or actively ignore)
mails sent to the list - "but you don't have to read my message" is *not* a
valid reason to continue writing off-topic messages.
