有没有办法在Scala反射中将两个等效类型转换为两个相同的类型？

scala> import scala.reflect.runtime.universe._
import scala.reflect.runtime.universe._

scala> typeOf[Boolean]
res23: reflect.runtime.universe.Type = Boolean

scala> typeOf[scala.Boolean]
res24: reflect.runtime.universe.Type = Boolean

scala> res23 == res24
res25: Boolean = true

scala> typeOf[java.lang.Boolean]
res26: reflect.runtime.universe.Type = Boolean

scala> res23 == res26
res27: Boolean = false

scala> class Foo { def bf(arg: Boolean) = ??? }
defined class Foo

scala> typeOf[Foo]
res28: reflect.runtime.universe.Type = Foo

scala> res28.member(newTermName("bf")).asMethod
res30: reflect.runtime.universe.MethodSymbol = method bf

scala> res30.paramss.head.head
res31: reflect.runtime.universe.Symbol = value arg

scala> res31.typeSignature
res32: reflect.runtime.universe.Type = scala.Boolean

scala> res32 == res23
res33: Boolean = false

scala> res32 =:= res23
res37: Boolean = true

因此,通过typeOf [Boolean]函数获得的类型等同于通过检查方法获得的类型,但它不相等.

有没有办法将两个等价类型转换为结果相等的某些规范表示？我希望能够将它们用于地图中的键.

编辑：

更清楚的是,我正在寻找的是(不是真正的repl会话)：

scala>val tp1 = // some type
scala>val tp2 = // equivalent type obtained another way
scala>tp1 == tp2
res1: Boolean = false
scala>tp1 =:= tp2
res2: Boolean = true
scala>val ctp1 = tp1.canonical
scala>val ctp2 = tp2.canonical
scala>ctp1 == ctp2
res3: Boolean = true
scala>ctp1 =:= tp1
res4: Boolean = true
scala>ctp2 =:= tp2
res5: Boolean = true

因此,转换会保留等价.我还需要它来处理参数化类型.
