219 ///
220 /// \code

233 /// statements whose name is dependent. All non-dependent cases are handled
234 /// directly in the parser, so that they don't introduce a new scope. Clang
235 /// introduces scopes in the dependent case to keep names inside the compound
236 /// statement from leaking out into the surround statements, which would
237 /// compromise the template instantiation model. This behavior differs from
238 /// Visual C++ (which never introduces a scope), but is a fairly reasonable
239 /// approximation of the VC++ behavior.
