I agree it's redundant if the type name occurs twice in the same statement. However, further evolution of the code often causes the instantiation to be moved elsewhere, and I wouldn't have confidence that the one doing that change then also changes `var` back to the type name. Instead, it would be nice to have syntax avoiding the duplication in the fashion of `FooBarBazThingyWithALongName thingy = new(...constructor parameters...);`.
Ideally linting tools on PRs show the refactored code as a violation, and it should be easy to rip a cleanup refactoring across the files before submitting a PR to avoid that.
