Lisp

Is there a lisp with manual memory management? I.e. with the ability to choose between pass-by-value and pass-by-ref, to free and allocate memory, to choose what gets allocated on heap, stack, registers, to choose the memory layout of structs, etc?

Oh yes, I have a PhD in Math, Comparitive Literature, and working in my PhD in CS. I'd post the papers with proof of what I'm talking about, but Abelson-san personally murdered the last person to do that.
