scala - Type mismatch; result.type (with underlying type T) with -Xstrict-inference compiler option -


i'm trying enrich scala.util.try type fold method. have following implicit that:

implicit class foldabletry[t](tryable: try[t]) {   def fold[x](failure: throwable => x)(success: t => x): x = {     tryable match {       case success(result) => success(result)       case failure(ex) => failure(ex)     }   } }

when run sbt compile -xstrict-inference compiler option, following error:

type mismatch; [error]  found   : result.type (with underlying type t) [error]  required: t [error]         case success(result) => success(result) [error]                                         ^ [error] 1 error found [error] (compile:compile) compilation failed

how can fix error? if remove compiler flag compiles.

it looks you're running bug (si-6680). recommend against using -xstrict-inference sounds experimental—notice paul phillip's comment:

-xstrict-inference intended coarse hacky start, kind of coincided departure. expect overflowing implementation issues.
