 	if( ( id->id_type == NULL) ||
 	    ( ( id->id_type->x_what == xt_arrayof) &&
	      ( item->x_left->x_what == xt_arrayof) &&
	      ( id->id_type->x_subtype == item->x_left->x_subtype) &&
	      ( id->id_type->x_flags & XIS_DIMLESS)))

or, less prettily, something like:

 	if(    ( id->id_type == NULL)
	    || (    ( id->id_type->x_what == xt_arrayof)
		 && ( item->x_left->x_what == xt_arrayof)
		 && ( id->id_type->x_subtype == item->x_left->x_subtype)
		 && ( id->id_type->x_flags & XIS_DIMLESS)
	       )
	  )

PS: The second example is included for those without a "showmatch"
option or unable to use "%" effectively in "vi", and with a
penchant for needing operators at the front of the line, due to
a crippling injury by an HP calculator in their youth, leaving them
unable to reasonably program in non-RPN languages, like "C", yet
unwilling to stick to "FORTH", where they belong.
