Using various types in a 'using' statement (C#)

Question

Since the C# using statement is just a syntactic sugar for try/finally{dispose}, why does it accept multiple objects only if they are of the same type?

Answer 1

There's no particularly good technical reason; we could have come up with a syntax that allowed multiple declarations of nonhomogeneous types. Given that we did not, and there already is a perfectly good, clear, understandable and fairly concise mechanism for declaring nested using blocks of different types, we're unlikely to add a new syntactic sugar just to save a few keystrokes.
