I certainly do use templates. Not sure how you get "don't use templates" from what I
wrote. Heck, I *over* used templates in the first large C++ project I ever did, and boy, does that
make a mess! Now I think I am down to a happy medium. I don't see them as "competitive"
(in a design sense) with macros.
Overusing as in template meta-programming?

The XL C++ compiler is withering on the vine. The word is that IBM don't
the resources to keep it up to date with the current standards so the
xlclang++ port of clang using the existing Toby back-end is the way to
go. If you use PDS data sets for your source your SOL as it's z/OS UNIX
only and only produces 64-bit modules.
But what I find exciting is that IBM have stated their intentions to
fully port LLVM/clang/libc[++] to z/OS without a reliance on LE so
supervisor state programming in C++ will be a reality without the
nightmare of LE ESPIE/ESTAE condition handlers.

I am generally not a fan of meta languages at all. I think writing programs is
hard enough, without having to write two effective programs: one that runs at
compile time and one that runs at run time.
In my C++, which is now my primary language, I eschew the use of C macros as
much as reasonably possible. Reasonableness is a key here. For a few things,
macros make sense.
That's interesting. You don't use templates which are one the most
powerful features of C++?
