Ok, so now, there's more use of
pexpr <- expr;
required. However this cannot work for compact linear types at the
moment because there are no pointers to components of such types.
So assignment is still mandatory for that. Otherwise assignment
should only be used for whole variables.
Pointer calculations are much better than value calculations sometimes.
Consider
set (a, i, v)
seems nice, for setting an array. But what if you have an array of arrays
and want to set one element of one inner array?
You would have to do this:
var col = get(a, i);
set (&col, j, v);
set (&a, i, col);
Clearly:
(&a) . i . j <- v;
is more readable and more efficient.
