sealed trait LinterLevel extends AnyRef

Controls the kind of linting performed during task macro expansion. The linting level is controlled by implicitly bringing an instance of LinterLevel into scope:* 

val foo = taskKey[Unit]("")
val bar = taskKey[Unit]("")
// This compiles because of the import in the block
val fooTask = {
  import sbt.dsl.LinterLevel.Ignore
  Def.task {
    if (true) bar.value
    else bar.value
  }
}
// because the import above was in a local scope, it does not apply here, so this won't
// compile:
//val barTask = Def.task {
//  if (true) foo.value
//  else foo.value
//}

import sbt.dsl.LinterLevel.Ignore
// Both defs compile because the Ignore LinterLevel is implicitly brought into scope and
// picked up by both task defs underneath
val newFooTask = Def.task {
  if (true) bar.value
  else bar.value
}
val barTask = Def.task {
  if (true) foo.value
  else foo.value
}

To make this work, the instances are all defined as implicit case objects. Moreover, the the LinterLevel.Warn setting is made default by placing LinterLevel.Abort and LinterLevel.Ignore using the low priority trait pattern.
