You need <type_traits> in both places now, for add_lvalue_reference_t. Otherwise the modules build breaks.

Include <type_traits> for add_lvalue_reference

Fixed. Good spot, @Quuxplusone.

@Quuxplusone do you want to land this and then have https://reviews.llvm.org/D108400 rebase with it or just pursue https://reviews.llvm.org/D108400 instead of this? CI just passed for this diff.

Once D108400 gets the OK from @ldionne I'll land it. If D108393 lands first, I'll rebase. If D108400 lands first, I'll close D108393. I don't think it matters whether D108393 is landed or not.

Fair enough. I don't have commit rights, so I'll need someone else to commit this on my behalf if we want to land this standalone.
