G'day chromatic / p5p / p6l,
Make a list of all possible types of exceptions, define them as roles, and
group them that way. Any given exception can implement multiple roles (:CORE
and :io, for example, or a specialization of that role that also does :USER).
Excellent point. I've been
If a routine is rw, you may optionally define a single slurpy scalar
(e.g., '*$value') in its signature.
A good start, but why limit the Lvalue to a scalar? A list l-value seems like a
pretty useful thing to me.

Officially, Num is the autoboxed version of the native floating point

The sqrt(2) should be a Num of 1.414213562373 with the precision of the

That makes the Num type an Int with non-uniform spacing.

I don't know what you accept as an infinity but

I don't know why he's calling it an Int with non-uniform spacing
unless he is complaining about what happens when you store ints in
floats: it rounds off to the mantissa size.
With uniform spacing you have

One little problem at the outset here is that Perl 6 has almost no

to choose to import certain subs into the user's scope by default.
