foo.dynamicType is broken for other reasons.  I see x.dynamicType as being a named operator (like sizeof) and not a property.  For example, we don’t want .dynamicType to show up in code completion on every value in the universe ("4.dynamicType”, really?).

That argues that it should be spelled as dynamicType(x), and ideally being a standard library feature instead of a keyword.
