I haven't used it but there is Orange:

I think it will be included in Phobos.

If the input is exactly in the format that a library like Orange 
expects, then it's easy.

To me, constructing an object from user input is conceptually outside of 
OO, because there is no object at that point yet. It makes sense to me 
to read the input and then make an object from the input.

Depending on the design, the input may be rejected by the function that 
reads the input, by the constructor of the type, or by both.
