Erased but Not Forgotten: How Type Erasure Turns Scala's Free-Spirited Overloading Into a...

The Magnet Pattern in Scala uses existential types to avoid type erasure conflicts, allowing a single function to handle multiple parameter types flexibly.

When overloading methods in Scala, such as def f(p: List[Int]) and def f(p: List[String]), type erasure leads to the same erased signature at runtime.

Type erasure complicates program design because generic type information is discarded, making it impossible to distinguish between methods that rely on different generic types.

In Scala, the JVM cannot differentiate between List[Int] and List[String] after type erasure, causing issues when compiling overloaded methods with conflicting definitions.
