By the way, since you are specifically asking about idiomatic D,
the common prefix "S_" in enum members is unnecessary in D, since
D already punts these in a separate name space. I can immagine
you'd prefer to keep things like it is to have some uniformity
among back ends, but if D were the only one you could do this
instead:
enum S {
YYEMPTY = -2, /* No symbol. */
YYEOF = 0, /* "end of file" */
YYerror = 1, /* error */
/* ... */
input = 14, /* input */
line = 15, /* line */
exp = 16, /* exp */
}
And refer to enum members as S.YYEOF (instead of S_YYEOF in other
back ends).
