This is untrue; vstruct can read into dictionaries and is primarily
meant to do so:

>> coords = vstruct.unpack(buf, "x:u4 y:u4 z:u4")
>> print("Coordinates:", coords.x, coords.y, coords.z)

Any field or subtable can be assigned a name. It's only the ones you
don't give names to that go into the array-part of the table.

In which ways do you think the documentation should be improved? Are
there parts that are unclear? Would you like more code examples?
