When the -XUnicodeSyntax option is specified, GHC accepts some Unicode characters including left/right arrows. Unfortunately, the letter "greek lambda" cannot be used. Are there any technical reasons to not accept it?
The "greek lambda" is a normal lower-case alphabetic character - it can be used in identifier names.
But it could be a reserved word synonymous with \. After all, \ can occur in operator symbols, but the operator \ is reserved.
