Computation between scalars #199
Description
I find it super-annoying that we're unable to use our operators to operate on scalars. Should we support ewise_add, ewise_mult, ewise_union, and apply on scalars? Also, support normal infix rules, such as s + 1. But, should these return expressions? Do we even dare to consider masking?
We can do this. We can use s._as_vector() to efficiently do this on GrB Scalars in SuiteSparse:GraphBLAS (other scalars would incur a copy into a new size 1 Vector).

I think a big selling point for doing this is to allow users to more easily see what operators do. For example,
unary.exp(1)orbinary.plus(1, 2).jim22k commentedon May 21, 2022
Yes, let's do this.

Given scalars
sandt, I think we can support multiple syntaxes:binary.plus(s | t)binary.plus(s | t, left_default=10, right_default=10)binary.plus(s & t)binary.plus(s, t) # same as binary.plus(s & t)s.ewise_mult(t, "+")I don't think masks make sense (for now). We may be able to support
s.selectwhere the first index is always0(mathematically, it's probably more correct to have no indices at all).
