Anonymous Recursive Functions in Racket

- Anonymous recursive functions allow recursion without explicitly naming the function.
- Racket's `lam/anon` macro binds `$MyInvocation` for anonymous recursion, mimicking PowerShell.
- Examples in `client.rkt` demonstrate `lam/anon` usage, including factorial, Fibonacci-like sequences, and nested functions.
- Anonymous recursion simplifies coding by avoiding the need to refactor lambda functions into named forms like `letrec`.
- Racket's `rec` form offers a similar solution, allowing named recursion with minimal syntax changes and preserved lambda features.
- PowerShell's `$MyInvocation` and Forth's `RECURSE` keyword are cited as inspirations or parallels for anonymous recursion.
