Whatever, and the dwim is, as you say, lazy. Or perhaps this generalizes
to an odd form of currying:
replicate := * xx 42;
Ohh, let me get that in my own words: the rhs replicates a Whatever
into

And how about

say @a[$i]; # prints 5 6 7 8?
The rational would be that the -1 goes
into the range Whatever value, that is
when it comes to expanding it inside the
array

How far can we drive the dwimmy use of the three values
that determine array access, i.e first and last index and
length. E.g. would @x[*+0..*/2] roughly slice to the

Hmm, this might not work. It should be @x[*+0..*-1-*/2]
on the footing that the last * is dwiming the length.
This implies that dispatches to infix:-:(Whatever,
Whatever) and infix/:(Whatever,Int) are supported
