Note: testing for erasure here is important, as it is many times faster than <:< and rules out most comparisons.

A ClassTag[T] can serve as an extractor that matches only objects of type T.
A ClassTag[T] can serve as an extractor that matches only objects of type T.
The compiler tries to turn unchecked type tests in pattern matches into checked ones
by wrapping a (_: T)
type pattern as ct(_: T)
, where ct
is the ClassTag[T]
instance.
Type tests necessary before calling other extractors are treated similarly.
SomeExtractor(...)
is turned into ct(SomeExtractor(...))
if T
in SomeExtractor.unapply(x: T)
is uncheckable, but we have an instance of ClassTag[T]
.
