Do we need an API method "SLICE", as extension to AT-POS?

[lizmat]

Sometimes I feel the absence of a SLICE method, essentially doing:

method SLICE(@pos) {
my @values;
@values.push(self.AT-POS($_)) for @pos;
@values
}
Making this part of the internal API, would allow for several optimizations, e.g. when working on fully reified lists / arrays and given a Range.

while low level for many uses, i am a big fan of slice as an all encompassing low level api for lists, arrays and so on … definitely support this idea

Yes please. I've thought about supporting Array access on Noun objects in Inline::J, and a SLICE method that receives all the positions requested would be very useful.
