Comment:
I removed the claim on the Haskell-prime wiki, and also removed the failed
attempt to support unicode lambda from GHC.
Further discussion is needed here: since λ is a lower-case letter, λx is
an identifier. If we want to treat this as meaning `\x`, that means λ
would need to be treated as a "special" character (like parentheses for
example). No other alphanumeric character has this property, currently.
