Are C ++ meta templates required for programmers?

Question

In my experience, meta templates are really funny (when your compilers are compatible), and can give good performance improvements, and, fortunately, I am surrounded by experienced C ++ programmers who also metaphor meta templates, however sometimes a new developer comes in and cannot do the heads or tails of some of the meta-template tricks that we use (mainly material from Andrei Alenksandrescu) for several weeks until it is triggered accordingly.

So, I was wondering what is the situation for other C ++ programmers? If meta-template programming should be something like a C ++ programmer, do you need to “know” (with the exception of entry-level students, of course), or not?

Edit: Please note that my question is about production code, not small samples or prototypes

I encourage people to learn how to use some of the features of STL . I used this library in production code, and it saves time and simplifies things quite a bit. I also roll back when such a need arises.

I also heard well about the boost library .

If I need to write portable code, I will usually stick with patterns, because many compilers still do not support them properly. If you need a portable STL, then STLPort is the most portable.
