Is it true that user defined types are resolved to ScopeDsymbol and basic types aren't?

a basic type does not need to introduce a scope since it has no members. All operators on them are supported natively and are no modifiable, so yes certainly.

From that (here I go OT) we can imagine a version of D with no basic integer types but just ubyte, and everything would be handled with operator overloads. All the other numeric types can be expressed using ubyte[<someLength>] in some structs, although not very convenient for the C interop.
