#11012: Support for unicode primes on identifiers. -------------------------------------+------------------------------------- Reporter: ghartshaw | Owner: Type: feature | Status: new request | Priority: low | Milestone: Component: Compiler | Version: 7.10.2 (Parser) | Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- GHC should allow the (single/double/triple/quadruple) prime characters in Unicode to be allowed in identifiers. This would make them consistent with the ASCII apostrophe, which is usually used in place of a single prime. The current workaround for primes (using one or more apostrophes) is unwieldy for higher primes (e.g. {{{a'''}}} and {{{a''''}}}). All of the following identifiers should be valid. {{{ a' // U+0027 APOSTROPHE a′ // U+2032 PRIME a″ // U+2033 DOUBLE PRIME a‴ // U+2034 TRIPLE PRIME a⁗ // U+2057 QUADRUPLE PRIME }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11012 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
