> Hello, In my old memories, I recall that [Ada (programming language)](https://en.wikipedia.org/wiki/Ada_(programming_language)) provide a concept of “range” for checking that a numerical value stored in a variable is always between a lower bound and an upper bound. This kind of check, is done at run time. I wonder if this kind of mechanism currently exist in Julia. For example I would like to say that I store an unsigned integer 8 but that upper bound can’t be upper than 10 and lower bound must be greater than or equal to 1. I only find information …
