It won't help. BeOS has been said to be a good OS. It is written
in C++. It hasn't been a huge commercial success. Does the fact that it
hasn't supplanted either Windows or Linux say anything about
whether C++ is a suitable language for OS construction then?

When Plan 9 was planned, the plan included Modula 2 as the
programming language to be used for the kernel. One of the
developers didn't say No but that he was so familiar with C
that he wished the kernel to be written in C. At least this
is part of the story, afaik. Does this say something about
whether Modula-2 is a suitable language for OS construction?

I think this issue needs a multivariate analysis.
