Already exists.  Just call var_create().

The case_idx isn't really there conceptually, because currently
it's thought of as part of the dictionary and just stored in the
variable for convenience.  But you can put it there with
var_set_vardict(); despite the stern warning in vardict.h that
"This header file should only be included by variable.c and
dictionary.c," there is nothing actually enforcing it (if I
recall correctly).
