#5108: Allow unicode sub/superscript symbols in both identifiers and operators -------------------------------------+------------------------------------- Reporter: | Owner: mikhail.vorozhtsov | Status: infoneeded Type: feature | Milestone: 7.10.1 request | Version: 7.1 Priority: normal | Keywords: lexer unicode Component: Compiler | Architecture: Unknown/Multiple (Parser) | Difficulty: Unknown Resolution: | Blocked By: Operating System: | Related Tickets: Unknown/Multiple | Type of failure: | None/Unknown | Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Comment (by zardoz): I also stumbled into this when trying to use the modifier letter prime (U+02B9) and related modifiers. Supporting them in identifiers would be awesome. As for operators I don’t feel strongly either way. I was just confused about modifiers not working in identifiers, because they are classified as alphanumeric in the Unicode properties. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/5108#comment:14 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
