Hopefully the coding can be incorporated into the next release. I see no
need for switching the additional features on and off.

Access to the properties of rows and columns will enhance the syntax like

for { r in R } {
  for { b in B } {
    printf "%3s: ", b;
    printf "%6s, %9.3g, %6.3f, %9.3g, %6.3f\n", r, 
      con_cap[b,r].ub, con_cap[b,r].value,  # upper bound, value
      con_cap[b,r].lb, con_cap[b,r].dual;    # lower bound, dual value

Best regards
