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.
