operators or methodicals for short. It is written in the present tense for
simplicity but should be understood as the future conditional.)

[S32::Temporal] remove .daycount method - use $date - $start_of_epoch to obtain
a day count starting from a fix epoch
Modified:
In reading all of the discussion about Temporal, I have the uneasy
feeling that the current development work is falling into the same traps
as other languages. It seems to me that the underlying time-measurement
paradigm of the developers is too tightly focused on the Christian
Gregorian

Ok, so no fixed epoch, and arithmetic on Dates operates in integral days.
Sold.
It would be handy to have some predefined constants for some common epochs,
like JD, MJD, JD, etc. Those don't necessarily need to be in core for
6.0.0, though. Maybe a separate Date::Epochs module? Examples:
Ruby has a similar functionality that lets you define methods on an instance
object. Really, its how class methods are specified, you just put the class
name as the name of the object. Here is an example:
a = Object.new
def a.foo
puts foo and #{self}
end
They will stay on the object as long
That's lifetime of the object, which is still monkeytyping, just on a less
global level than modifying the class directly.
Compare the Ruby example to this: (syntax is entirely made up):
my $foo = SomeClass.new;
{
methodical bar(SomeClass) { say Hello, world! }
$foo.bar # Hello, world!

I whole-heartedly agree that we need to make a system independent of any
sort of time measurement system. I think the conclusion reached on IRC
was that most of the world uses or is at least familiar with the
Gregorian system.
Now, I can't help but think how we would define an Instant. The

I recommend not to open this up for 6.0.0 core. Calendar conversion
is easy to do in a module, and the Date class has an absolute day
count, which is really all you need everything for an intermediate
representation. It wouldn't be hard to port Calendrica, for
instance.
Also, the difference
