It may be that WG1 has conflicting goals. A minimalistic language would
have continuations but not excaptions; maybe a clock for seeding random
generators, but not the generators themselves; condition variables and
mutexes, but not mailboxes or other easier synchronization tools...

But a "small language for learning only how to do basic programming" may
need an exception system, and not continuations; RANDOM; mailboxes
for synchronization, and so on.

This is because it's not always the case that complex things are built
on top of simpler things. Quite often the opposite happens.

But in spite of that, I do like what the working group has done.
