Hi there,
I got a error when trying this piece of code:
my Int @s[0..10];
my $f =
A recent rakudo commit [1] is a quick fix for #78896 [2] to allow
exponentiation of Duration's.
I'm uneasy with allowing this and I think the spec probably meant not
to but is badly worded [3]:
Durations allow additive operations with other durations, and allow
any numeric operation with a numb

Therefore the multiplication of two Instant may results in diff

That's correct, and the reas
I'm not convinced that the type system shouldn't be helping with
dimensional analysis, but at least it shouldn't hurt. By all means,
let the programmer raise a Duration to a power - but the type of the
result should not also be Duration. In the absence of automatic
dimension tracking, just return

I still have uses for Durations.
For instance, I want to dispatch a different .Stringy method to Durations than
to Nums. It's convenient to me that the difference between two Instants has a
different type than the difference between 1654321681.123 and 1654321021.65438.
I just think Durations

If I'm following this correctly, shouldn't we just say that Duration
does Num? That way, a Duration can be used exactly like a Num is
(with units measured in seconds); but it could also have special
capabilities above and beyond what a Num can do, if such capabilities
are needed.
More generally,

Num is a class (think floating point number).
The role you're looking for is probably either Numeric or Real.
If we say that Duration inherits from Rat or FatRat, it automatica
