Scala 2.8 formalized the ability to encode type information into implicit parameters. Manifests were added specifically to handle arrays and generalized to be useful in other situations where the type needs to be available at runtime. In this article from chapter 7 of Scala in Depth, author Joshua Suereth shows how Manifests are useful in Scala to create abstract methods whose implementations diverge based on the types they work on, but the resulting outputs do not.

Scala is a language that blends various techniques seen from other programming languages. This article from Scala in Depth explains how Scala attempts to leap between the worlds by offering its developers object-oriented programming features, functional programming features, a very expressive syntax, statically enforced typing, and rich generics—all on top of the Java Virtual Machine.
