Extended Description

Created an attachment (id=976)
source code to reproduce fault
I tried adding a last-axis catenate to ArrayTransform.xsac, like this:
z = with {
        (0 *_shape_A_(x) <= iv < _shape_A_( x)) : x[ iv]; 
        ,
        ( offset <= iv < shpz) : y[ iv - offset];
      } : genarray(shpz, -666);
However, -bscp sticks a comma after each partition, which sac2c does not like.
This is what comes out of the -bscp sausage-maker:
 z = with {
        (*( 0, _shape_A_( x)) <= iv < _shape_A_( x))
        {
        } : sel( iv, x) ; ,
        (offset <= iv < shpz)
        {
        } : sel( -( iv, offset), y) ;
         } :
      genarray( shpz, zero( x));
sac2c does not like the comma.
I suppose I can break up the WL into a genarray/modarray pair...
