Calling match in a clang-tidy check's check method

Is there a way to get a non const reference to the ASTContext inside of a clang tidy check? I have two reasons I want this.

1. To do matches on specific nodes like below.

void MyCheck::check(const MatchFinder::MatchResult &Result) {
  auto const *Lambda = Result.Nodes.getNodeAs<CXXRecordDecl>("Lambda");

  // Doesn’t work because Context is a const* and match has no const overloads
  auto BN = match(<more matchers here>, Lambda, *Result.Context);

2. To use the ExprMutationAnalyzer in my check function, which requires a non const ASTContext reference for its constructor.
