### Extending Hindley Milner with (mutual) recursion

What's a good approach for extending Hindley Milner with mutual recursion without de-sugaring to let+fix+records? My thinking is (assuming no polymorphic recursion) Collect mutually recursive lets ...

### Can total (primitive) corecursion be implemented?

I'm trying to understand how to implement corecursion in a total functional context. I've already implemented recursion using standard techniques (for loops) but I ...

### Is there a generic way to refer to the current function in recursion?

In writing recursive functions (functional style), I often need to refer to the current function (depending on the context). e.g. f 0 = 0 f (S n) = f n + 2 Are ...

### X86-64 Assembly for Recursive Functions

A compiler I'm writing generates the following x86-64 assembly (AT&T syntax) for a recursive factorial function. I convert the assembly into an ELF executable using ...
