Records depend on the preprocessor, and therefore introduce a
compile-time dependency between modules. When using e.g.
property lists, which are admittedly slower than records, adding
a new property is easy. If you use a record, the users of the API
must recompile in order to be compatible, even if they don't
use the new option.
