PICL - PICL Is Crustacean Lisp

==============================

A LISP written in Rust.

The idea is to write a core in Rust that is just enough to bootstrap the rest

in PICL itself.

### Design ideas wish list

- Simple, consistent API for data manipulation a la Clojure.

- Simple pattern matching (more like destructuring)

- Regex literals `/.*(a|b)/` a la AWK?

  - Following the EDN syntax this should be `#r".*(a|b)"` to signify the start

  start of a regex as a reader level tag.

  - Alternatively, I have always really liked Julia's string macros work

  which seems similar to CL's reader macros and Hy's tag macros:

  ```

  (deftag my_tag (expr) `(~expr ~expr))

  ```

  - In Julia they are defined simply as any macro that is named as a single

  character followed by `_str`. They then get applied when that character is

  prepended to a string literal

  --> `r"a regex literal",  f"x = 3y + 2"`

  - The reader/tag macros on the other hand match the EDN idea and are defined

  as `(defreader ...)` or `(deftag ...)` and then called like so:

  --> `#my-tag FORM`

  - They allow for longer tag names but not the nice string application.

  - ...TBH, why not both?!
