Hello.
I want to both start either { … } block and catch any exceptions inside like:

either {
    Either.catch {
        // potentially throwing code
    }.bind()
}

Is there a builtin function for such case? something like

eitherCatch { … }

Such a function is not available yet, and you need context receivers to define it 😕

We're working on such functions though, but since working with Either is typically over E the function is currently prototyped as:

either<Error, A> {
  val a: A = catch(
   { // throwing code },
   { e: Throwable ->
     // shift(e.toError())
     // transform(e).bind()
     // return fallback A
   })
   a
}
