That's right.
But I guess it can be a
runtime calculated value, acting like it was assigned in a a static
this() clause,
No, that's not ri

But actual value of that Regex struct is perfectly known during
compile time. Thus it is possible and fine to use it as
initializer. You can use any struct or class as initializer if
it can be computed during compile-time.
Yes, regex

At seconds PER (character range) pattern, ctRegex slows down
compilation like crazy, but it's not obvious how to avoid using
it, since Regex(Char) is kind of weird for a type. So, here's
what I do. I think this is right.
