my &a = *+1;
my &b = */2;
say &a.arity; # 1
say &b.arity; # 1
say (&a o &b).arity; # 0
say &a.count; # 1
say &b.count; # 1
say (&a o &b).count; # Inf
Ideally, the result of the `o` operator should probably have the same
signature as its right-hand argument (which gets the input "first").
Things that care about arity/count, and thus might currently behave
differently than users expect when given a Block created by `o`,
include:
.sort (comparator vs Schwartzian transform)
.map (normal map vs n-at-a-time)
o (interpolates input lists if count>1)
