So while it is executing the regex building at compile time in
your example, there are other ways to do it, and in this case,
I'd prefer using an enum. You can also use ctRegex.
The drawback of using static is that it keeps its value between
function calls:
What about static immutable? I think enums exist only for
compiler but they're not a l-value, so you can't take a
reference, am I wrong?
