- def binderTypeImpliedByPattern(pat: Global.Tree, pt: Global.Type): Global.Type
Compute the type T implied for a value
vmatched by a patternpat(with expected typept).Compute the type T implied for a value
vmatched by a patternpat(with expected typept).Usually, this is the pattern's type because pattern matching implies instance-of checks.
However, Stable Identifier and Literal patterns are matched using
==, which does not imply a type for the binder that binds the matched value. E.g., incase x@Nil => x, all we know aboutxis that it satisfiesNil == x, which could be anything. A type pattern with a literal type works the same as the corresponding literal pattern. A literal pattern with a Boolean or Unit pattern does enforce that the respective value (true,false,()) was matched, so in those cases, the pattern type is assumed.The other patterns imply type tests, so we can safely deduce that the binder has the pattern's type when the pattern matches. Concretely, a literal, type pattern, a case class (the constructor's result type) or extractor (the unapply's argument type) all imply type tests.
