229 /// directly in the parser, so that they don't introduce a new scope. Clang
230 /// introduces scopes in the dependent case to keep names inside the compound
231 /// statement from leaking out into the surround statements, which would
232 /// compromise the template instantiation model. This behavior differs from
233 /// Visual C++ (which never introduces a scope), but is a fairly reasonable
234 /// approximation of the VC++ behavior.
