This seems wrong to me. It is not generally possible to convert a
String into a Date. Also, the type lattice doesn't permit that
conversion. Type inference is supposed to yield a typing of which the
automatic type conversions that it imposes during run time work
without exception. We should not misuse the conversion method to build
a customized parser.
