During a project development, I have encountered this weird function syntax
fun <T: Any> boo() { do something}
I am aware of T indicates a generic type and Any is a root class of all class in Kotlin and : implies class inheritance or interface implementation but what is T: Any?
T : SomeType sets the upper bound of the generic type. T would have to either be SomeType or be some sub-type of SomeType.
In this case, T : Any sets the upper bound to be Any. While that may seem pointless, it does mean that T cannot be nullable.
