It would be more or less trivial for Jython to add such support, given that
Java has such support natively, and we already leverage this support in our
current implementation of 2.7. See
https://docs.oracle.com/javase/7/docs/api/java/lang/Double.html#valueOf(java.lang.String)
if curious. We just need to add the correct floating point constant that is
parsed to Java's constant pool, as used by Java bytecode, and it's done.

I'm much more concerned about finishing the rest of 3.x.
