I thought unary + was scalar/item? context in perl6, not numify.

When in doubt, check the spec. :)

S03 (])​:

So prefix​:<~> stringifies, prefix​:<+> numifies, and prefix<?> boolifies.
There's some kind of nice symmetry to that, isn't there?

 + is numeric context - which is one of several subtypes of item
context. Generic item context is item(); + numifies; ? boolifies; ~
stringifies.

I'm guessing you saw + used to get the length of an array, and that's
where you got that it's equivalent to P5 scalar().
