GAP seems to have some problems whenever doing an assignment or
arithmetic operation to an element of a list which is represented as a
range with a negative difference.

For example:

gap> a := [10,8..2];
[ 10, 8 .. 2 ]
gap> a[3] := a[3] + 4;
10
gap> a;
[ 10, -2, 10,, ]

Is there any way to force GAP to represent a list using the ordinary
list representation, instead of the compact range representation, even
when GAP has realised the list is in fact a range?
