In Scala, method signature semantics goes beyond method name, parameters and result type. The signature can also tell about whether a method has side effects, or whether a method represents a property.
However, sometimes we forget about writing proper definitions or method calls. That’s where 15 new method signature inspections may help.

Inspections are one of my favorite features in IntelliJ and my experience with these Scala Inspections has been very positive. They go beyond what is possible in Java inspections because they talk to how you should use an API or whether or not a var is necessary. In effect these Inspections seriously help the team write idiomatic Scala code which is better for everyone
