Well, I don't know what you looked at, so I guessed.  If the criterion
is indeed how long it took implementations to move to R5RS to R6RS, I'd
welcome you to look at how long it took implementations to move from
R4RS to R5RS.  If that's a fact that measures community acceptance for a
standard, then R5RS was an abysmal failure, and you should start with
something earlier.

So the criterion is "attempt R5RS compliance".  But for Guile:

... it is not?  What's the criterion for "attempt"?

Anyway, I've said my part, and this is the extent to which I care.  It's
your funeral.
