If you are afraid your constant is not constant expression put a static_assert. Then remove.

  How do you measure "work'?

In lines of code. Imagine you would specialize a container like
unordered_map by hand in C. That would be days of work. In C++
it's one line of code and you get nearly optimal performance.
Or just think about what an emplace_back on a vector of strings
all does; if the capacity isn't sufficient a doubled vector is
allocated (libstdc++, libc++), all objects are moved there and
a new item is emplaced at the end. That's one line of code, but
in C that's a half day's work.
