#14812: Dot-Notation for Flipped Function Application -------------------------------------+------------------------------------- Reporter: tepan | Owner: (none) Type: feature request | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.2.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by AntC): Replying to [ticket:14812 tepan]:
Please allow to put a dot `.` (without whitespaces) between two things for ''flipped'' function application. This could make for code in pseudo- OOP style:
Great idea! It's been suggested many times, including by SPJ https://prime.haskell.org/wiki/TypeDirectedNameResolution; and especially to represent field application to a record or struct, similar to OOP https://ghc.haskell.org/trac/ghc/wiki/Records/DeclaredOverloadedRecordFields.... Sadly, it was shot down in flames; because it seems there's lots of code using dot as function composition not surrounded by whitespace -- for example, it's a common idiom with lenses. But I think worth asking again. As others have said, please submit a proposal on github. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14812#comment:11 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
