The same substitution identifier must take the same number of argument across all substitution groups.
       Example:
           [
               ident1(arg1, arg2)  [sub1 arg1 arg2]
                      ^^^^^^^^^^
           ]
           [
               ident1(arg1, arg2)  [arg1 arg2 sub2]
                      ^^^^^^^^^^
           ]
