What you are looking for is _tail call elimination_ (also called as tail call optimization or tail recursion optimization). There have been a number of threads on the subject here, e.g. [this one](https://discourse.julialang.org/t/tail-call-recursion/87847). According to this discussion, “Julia doesn’t have tco currently, and is fairly unlikely to add it.” That being said, a macro is being considered [on Github](https://github.com/JuliaLang/julia/issues/4964#issuecomment-961932928).
