Yes, I know.

Yes. Allow me to rephrase. When I was taught Ada, it was assumed that
Ada was used primarily by the US Department of Defense, who had a hand
its creation.

I like the fact that Ada is very strict, because it forces new
programmers to do things right. On the other hand, that comes at the
cost of flexibility, which makes it useless for certain tasks.

Since C predates Ada by at least a decade, I don't think C is the
problem. I have never had a problem keeping "==", "=" or "!="
straight.

It's just my opinion, but there are at least a 2 dozen languages that
use the same syntax. Programmers who spent a large part of their
careers in low level or embedded have no problems with it that I can
tell. I think the only ones who DO have that problem are programmers
who learned things like Pascal or Ada first, along with the new kids
who can't seem to program "their way out of a paper bag" without
resorting to OOP.

Example? Have a good laugh. I know I did.
