I am thinking about this. I am a bit worried because
if we would like another form of indexong number of
combinations may get large. So I consider alternative
of sort
LSI => List Segment Integer
IndexType ....
autoCoerce(LSI) -> %
-- maybe just coerce, would need to experiment to find
-- out which one gives better behaviour
autoCoerce(SI) -> %
-- maybe other variants
convert : (%, Integer, Integer) -> LSI
-- extra arguments to represent lower and upper bound
-- for matrix indices, needed if we want complement
and then define
elt : (%, Integer, IndexType)
elt : (%, IndexType, Integer)
elt : (IndexType, Integer)
The idea is that interpreter/compiler magic should convert
what needed to IndexType. I am special casing Integer as
oterwise we would get mismatch with normal array indexing.
It may require tweaking interpreter priorities for choosing
operations.
