I am proposing to introduce additional Unicode λ forms such as `case-λ`, `#%plain-λ`, and `match-λ[*][*]` to Racket, which seems like a minimal and safe change.

I would appreciate your thoughts on this proposal:

- Do you find these Unicode forms useful or necessary in your coding practice?
- Are there any potential issues or conflicts that might arise from introducing these forms?

I consciously avoid using non-ASCII characters in identifiers, but that’s just my two cents.

`#%plain-λ`: No. The `#%` prefix in `#%plain-lambda` indicates that it’s a kernel form, and we don’t need another one.

I agree with your point of view. In addition, `#%plain-lambda` is the `lambda` in the kernel. If we define `#%plain-λ` as the `λ` in the kernel, we may have a similar trouble: [Renaming mechanism for Unicode `λ` in Racket](https://racket.discourse.group/t/renaming-mechanism-for-unicode-in-racket/2910/1)
