Some --strict-optional code previously assumed that the
partial_types
list could only containPartialType
s. In some cases, it appearsAnyType
can also be part of that list. It's not entirely clear to me what causes this, but it looks like the correct solution is to be robust to the presence of other types in that list.Fixes #1948.
