Currently if you do
... = @a[...]
%b{...} = ...
to a tied array or hash, you get several separate FETCHes and STOREs.
For efficiency and/or semantic reasons you might want otherwise.
I propose adding new (optional) methods applicable to both arrays
and hashes, FETCHSLICE and STORESLICE, which are called thusly:
FETCHSLICE $this @indices
STORESLICE $this $nindices $nvalues @indices @values
For hashes one can read 'indices' as 'keys' if that feels more natural.
The $indices and $nvalues are needed since the left hand side
and the right hand side are not necessarily of the same length.
For hashes it might make more sense to have
STORESLICE $this $nindices @keyvalpairs
To get rid of the $nindices and $nvalues one might also consider
FETCHSLICE $this [@indices]
STORESLICE $this [@indices] [@values]
but I don't know whether constructing and dereferencing the anon
arrays would be too costly.
Implementation? Hey, I'm the proposer, okay?
