Yes. For the sake of completeness, any expression needed at
compile time will be (attempted to be) executed at compile
time. For example, an expression used as a template parameter
will be executed at compile time as well.

That's not true. It all depends on how the expression is
needed. If for example, the variable were defined as enum, the
compiler had to execute the code at compile time to compute its
value.

That is unnecessary and hurts readability. :/ Most programmers
see string mixins as a last resort.
In any case, some people may find a compile-time file parsing
example that I included in a presentation:

Thank you Ali for the clarifications
