Parse and validate simple name/value option pairs
Hashes are great for storing named data, but if you want more than one entry for a name, you have to use a list of pairs. Even then, this is really boring to write
@values = foo => undef, bar => undef, baz => undef, xyz => … , ;
With DataOptList, you can do this instead
DataOptListmkopt[ qwfoo bar baz, xyz => … , ];
This works by assuming that any defined scalar is a name and any reference following a name is its value.
