Pointers have to be the first thing to go. And of course array bounds
should be checked, but all that can do is crash a program, which was
going to crash sooner or later anyhow.

We are programming antique hardware in antique languages.

The ideal programming language would be wordy, plodding, not a bit
exciting - sort of like Cobol - and no fun for research or for coding.
That's the point: we have to make programming not fun if we want it to
be reliable. Modern programming attracts the wrong kind of people to
teach and do reliable programming.

When later versions of programs are slower and buggier, "the market"
will oblige by not upgrading. We have seen this here a few times - a
new rev is worse than the current one - so we drop support and stick
with the one that works. Or we go to a free equivalent, like PDF
utilities or LT Spice, and dump the bloatware.
