binderTypeImpliedByPattern(pat: Global.Tree, pt: Global.Type, binder: Global.Symbol): Global.Type
Compute the type T implied for a value
v
matched by a patternpat
(with expected typept
).Compute the type T implied for a value
v
matched 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.See scala/bug#1503, scala/bug#5024: don't cast binders to types we're not sure they have
TODO: update spec as follows (deviation between
**
):A pattern binder x@p consists of a pattern variable x and a pattern p. The type of the variable x is the static type T **IMPLIED BY** the pattern p. This pattern matches any value v matched by the pattern p **Deleted: , provided the run-time type of v is also an instance of T, ** and it binds the variable name to that value.
Addition: A pattern
p
_implies_ a typeT
if the pattern matches only values of the typeT
