Dict type-following

Prior to this, when you accessed methods that were part of a dictionary the type following wasn't done correctly. This release will update to code that does this correctly.

Note this is still now working correctly for tuples!

What's Changed

• Type propagation through dict and tuples by @gordonwatts in #140
• Deep-Type Dictionaries by @gordonwatts in #142
