UUID(Flag!"random", ... ) is just ugly. It's far better to use a
static function with a descriptive name.
These functions are _constructors_; ideally, they should be expressed as
such. In a managed language, we'd probably for with UUID("random",...).
And if explicit template ctors were valid syntax, we'd used
UUID!"random"(...) or UUID!Mt19937() or UUID!randomNumberBased or
something. There's also the enum/aliases, i.e. UUID(UUID.random) or
UUID(Enum!"random") or UUID(UUID.Version.randomNumberBased). And at
least for random, overloading works decently well, i.e. UUID(mySeed) or
UUID(Mt19937(unpredictableSeed)). My point, or lack thereof, was to
brainstorm ways of expressing a large variety of construction routines
_as_ actual constructors.
The first item of the book "Effective Java Programming Language Guide"
says "Consider providing static factory methods instead of constructors".
But if you want to insist on actual constructs, I would prefer
UUID(UUID.random) instead of UUID("random",...) or UUID!"random"(...).
