Description
The --strictNullChecks PR changed some declarations in types.ts to avoid frequent assertions in the compiler's code. Unfortunately these changes make it really unsafe for API users because they no longer contain the actually nullable types: https://github.com/Microsoft/TypeScript/pull/22088#discussion_r184149465 https://github.com/Microsoft/TypeScript/pull/22088#discussion_r184155027
ts.Node#parentis no longer optional (which is definitely wrong forSourceFile)ts.Symbol#declarationsandts.Symbol.valueDeclarationare no longer optional, but can still be undefinedts.Type#symbolis no longer optional, but I guess this comment is still up to date:// Symbol associated with type (if any)
These changes should either be reverted or replaced in the published declaration files. /cc @andy-ms @weswigham
