Ah... right. Silly me. Of course, since string is actually
immutable(char)[].
That's bit of a nasty corner case where -> == . isn't that nice.
Fortunately, it's rare.
Thanks.
This happened to me, when I was packing stuff into SoA layout and
didn't want to duplicate the length in the struct (implicitly by
using []). Of course, I forgot to update one place to use the
shared length.
That is:
length
ptr
ptr
ptr
instead of
ptr
length
ptr
length
ptr
length
Perhaps I should do a SoA layout template that somehow disables
.length on individual arrays.
