{{{ Warning on declaring a partial record selector. However, disable warn with field names that start with underscore.
}}}
Eek. I may be too late. Don't the lenses people use underscore prefix on record labels? So that TH can detect that and produce a lens name with the `_` stripped off? Then they're going to miss out on this warning of partiality. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/7169#comment:29 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
