 understood.  i quite like the vector-masking programming model. the
Aspex ASP (Array-String Process) was however an absolute b*****d to
program (4096 2-bit SIMD maskable ALUs).  so... it's a faaairly big
compsci-sized deal :)

 hmmm... i have an idea, which always tends to help me: how would you
feel about writing an update for the crowdsupply campaign, about this?
just outline where things stand, what the end-goal is, and so on.
often i find that the more times (in different places) i talk about
stuff, clarity and ideas come.

 what you reckon?
