22. #### def resolveClassTag(pos: Global.Position, tp: Global.Type, allowMaterialization: Boolean = true): Global.Tree

    Finds in scope or materializes a ClassTag.

    Finds in scope or materializes a ClassTag. Should be used instead of ClassManifest every time compiler needs to persist an erasure.

    Once upon a time, we had an `ErasureTag` which was to `ClassTag` the same that `WeakTypeTag` is for `TypeTag`. However we found out that we don't really need this concept, so it got removed.

    pos

      Position for error reporting. Please, provide meaningful value.

    tp

      Type we're looking a ClassTag for, e.g. resolveClassTag(pos, IntTpe) will look for ClassTag[Int].

    allowMaterialization

      If true (default) then the resolver is allowed to launch materialization macros when there's no class tag in scope. If false then materialization macros are prohibited from running.

23. #### def resolveTypeTag(pos: Global.Position, pre: Global.Type, tp: Global.Type, concrete: Boolean, allowMaterialization: Boolean = true): Global.Tree

    Finds in scope or materializes an WeakTypeTag (if `concrete` is false) or a TypeTag (if `concrete` is true).

    Finds in scope or materializes an WeakTypeTag (if `concrete` is false) or a TypeTag (if `concrete` is true).

    pos

      Position for error reporting. Please, provide meaningful value.

    pre

      Prefix that represents a universe this type tag will be bound to. If `pre` is set to `NoType`, then any type tag in scope will do, regardless of its affiliation. If `pre` is set to `NoType`, and tag resolution involves materialization, then `mkRuntimeUniverseRef` will be used.

    tp

      Type we're looking a TypeTag for, e.g. resolveTypeTag(pos, mkRuntimeUniverseRef, IntTpe, false) will look for scala.reflect.runtime.universe.TypeTag[Int].

    concrete

      If true then the result must not contain unresolved (i.e. not spliced) type parameters and abstract type members. If false then the function will always succeed (abstract types will be reified as free types).

    allowMaterialization

      If true (default) then the resolver is allowed to launch materialization macros when there's no type tag in scope. If false then materialization macros are prohibited from running.
