Switch to non-deprecated calls

[cdenneen]

Utilize validate_legacy from stdlib

[pcfens]

Would you rather do it this way or change the input types to types?

[cdenneen]

That works too... I'm just trying to cleanup all the "deprecation" warnings I've been seeing while doing test runs... I would probably prefer to remove the legacy 3.x in place of actual types.

[pcfens]

Do you think you might have time to do that soon? If you do then I'll hold off on merging this. If you think it might be a bit then I'll go ahead and merge this so we'll have something and then we'll just see which of us gets to it first.

Thanks for bringing this one up.

#42 opened... not sure which you would rather.
Had to fix few spec tests using String of 'true' rather than Boolean value.

I'm going to close this since #42 is merged now. Thanks again for all your help.
