alex, dr kimmet: i... did try (partly on your behalf) to get across
to the RISC-V Foundation how... deeply unimpressed i was that RV64GC
had been chosen as the default unix standard without *any* kind of
wider consultation, not even with the RISC-V members.
unfortunately my usual direct, bluntly honest and completely
undiplomatic communications style, which i mirror in real life by
wearing 12 GBP steel toe-capped boots, bought from Douglas Dairy
Supplies in Stranraer, did not go down well.
