I still suspect it would not be outside the pale to make λ a keyword. We already have several, after all.
I'd rather not have to write \x as λ x with a space required after the λ. I suspect that "λ is the lambda-symbol iff it is not preceded by any identifier character and is not followed by a Greek letter" might work.
Adjacent different scripts in general is probably a reasonable token discriminator. A "token" combining LTR and RTL, for example, is just confusing.
