I think you've missed my entire point.
The summary is this:
Tried D, tried a very popular and often hyped D library/framework,
encountered bugs. There was friction along the way which undermines
confidence, but the critical point, the thing that caused the call to
be made, was that the debugger didn't work, and we were unable to
diagnose the bug with relative ease.
It's possible that wouldn't have inspired the call to be made if it
weren't for the prior friction... ie, if it were the first point of
friction, we might have persevered through that one, but the aggregate
prior to that point painted a clear picture, and that was the
proverbial straw.

Immaturity in the language seemed to allow for greater tolerance than
immaturity in the tooling.
This is the experience I was trying to convey... which was to be taken
as a case study, that is all.

Again, you completely missed the problem. I haven't said anywhere that
the language itself raised any particular issues.
It was the *tooling*. There were also numerous complaints about the docs.

I would happily challenge that bet.
I've learned Java, C#, python, js, lua, ..., by being told to get a
task done at work; expected to learn the languages within minutes and
produce a solution.
I never had any problems with this in the past.

The only language I've ever 'learned' was C, and that was 15-20 years ago.

I can and I did.
