That's right. Strong, strict type-checking and garbage collection
were known technologies and were embedded in programming languages
before OO. But they seem to have entered the main stream of popular
language use along with OO languages.

Yes.

No argument here.
I may have been condescending, but it did not seem to me that these
advantages were what was likely to be appreciated by a Fortran
programmer.

In any case, in my experience (which included writing a parser and
static type-checker for C++ in C++), these advantages of C++ do not
outweigh the lack of secure type checking and garbage collection.
