help: to declare that `Opaque(DefId(0:13 ~ impl_trait_captures[1afc]::foo::{opaque#0}), [ReEarlyBound(0, 'a), T, ReEarlyBound(2, 'a)])` captures `ReFree(DefId(0:8 ~ impl_trait_captures[1afc]::foo), BrNamed(DefId(0:12 ~ impl_trait_captures[1afc]::foo::'_), '_))`, you can add an explicit `ReFree(DefId(0:8 ~ impl_trait_captures[1afc]::foo), BrNamed(DefId(0:12 ~ impl_trait_captures[1afc]::foo::'_), '_))` lifetime bound
