There's two answers. In a world where we have const correctness, you shouldn't be able to (this is a misfeature on `Decl` that it has a `const` overload that returns a `const ASTContext &`). However, Clang inherited a lack of const correctness from the mists of time, so we have these sort of misfeatures still lurking (and will for quite some time). So for now, the recommendation is `const_cast` so it's clear where we're breaking const correctness. https://github.com/llvm/llvm-project/pull/130096 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
