Before bad value support was built into PDL, we implemented our own bad
value handling using NaNs to mark bad (or empty/missing) values as PDL
subclasses. Since we are handling bad values outside of the normal PDL
codebase, we are depending on the PDL bad-value support to NOT be on.

you do that?

options still necessary?
Some of the software I have that uses PDL extensively depends on the
PDL_WITH_BADVAL being zero (i.e. NOT using badval support).

Dear PDL devs,
Currently all of these options are configurable in PDL (albeit not
all combinations are meaningful):
* PDL_WITH_BADVAL
* PDL_BADVAL_USENAN
* PDL_BADVAL_PER_PDL
This set of combinations adds a significant cost to development, and
testing all the combinations.
Are all these options still meaningful? Is there still a context
where it is necessary to build PDL without bad value support?
I ask because if it’s no longer necessary, we can remove some code,
and make things easier for everyone.
Best regards,
Ed
