FYI, just as additions to _Alternative packages_, FoldsThreads.jl’s “trampoline” also uses the same technique (IIUC) [https://github.com/JuliaFolds/FoldsThreads.jl/blob/master/src/trampoline.jl](https://github.com/JuliaFolds/FoldsThreads.jl/blob/master/src/trampoline.jl). JuliaFolds packages in general also try to do a weaker version of this, as discussed in: [Tail-call optimization and function-barrier -based accumulation in loops](https://discourse.julialang.org/t/tail-call-optimization-and-function-barrier-based-accumulation-in-loops/25831)

(But it looks like you arrived at a more generic API/implementation, which is great!)
