Which schemes support, by default, the unicode lambda character as an alternative to "lambda"?
The following expression was evaluated on the REPL: ((λ () "ok")).
Of course, any Scheme supporting Unicode in identifiers and any form of symbol aliasing (syntax-case, for example, allows one to do that) could be programmed to translate unicode lambda in ASCII lambda. This shows the default behavior on the REPL only.
