In such a case, the Cis default just looks plain odd to me.
It is. More than that, it's plain wrong. Cis properties are

Properties are meant to be out-of-band information; miko's
suggestion would have this property setting the *value* of

Ah, but my exact point is that the default *isn't* set immediately. The
property is held until the sub is called. If the
It was settled a while ago that sub arguments would be defaulted like this:

I love the //= operator, but in the context of sub declarations it's
confusing as the *only* way to default an argument.

Oh. You want default() to be synonymous with //= but only in
subroutine declarations. That seems a tad odd. Why not make it
synonymous everywhere?
my $foo is default(23); # same as ...
my $foo //= 23;
Well, for is default to DWIM in a
