I found this especially confusing because the built-in Tuple is 
defined differently.

The Tuple in that example is equivalent to the definition of 
TypeTuple, and yet TypeTuple is supposedly specific to types 
while that example (as so by implication TypeTuple) apparently 
works just as well with other contents.

On top of that Tuple is the one that only works with types - any 
string expressions are extracted and used as names... Surely a 
tuple which can only store types should be a TypeTyple and a 
tuple which can store anything should be a Tuple.
