FS#128 - Mixed-type arrays
Currently, arrays may contain only one object type. Would be nice to eliminate this restriction and allow arrays to contain objects of different types.

If an array contains more than one type, how would you know the type of each cell ?
Mixed-type arrays look like a bad programming practice, or a kludge.
Could you provide an example which demonstrate the interest of having a mixed-type array ?
(one of my basic rule from kindergarten: do not mix apples & oranges)
Mostly the problem has occurred with multi-dimensional arrays as a way of storing input parameters to be used later, IIRC.
#local apples_array = array[3][3] { // name, color, radius {"Macintosh", x, 5}, {"Granny Smith", y, 3}, {"Golden Delicious", x+y, 4} }Seems solved from comments in FS#127
Those comments just recommend multi-dimensional arrays... which just happens to be what I provided in the example above. So, no, I don't think anything was "solved".
#local apples_array = array[3][3][1] { // name, color, radius {{"Macintosh"}, {x}, {5}}, {{"Granny Smith"}, {y}, {3}}, {{"Golden Delicious"}, {x+y}, {4}} }- solved.
