- use `$implicit` variable value correctly - handle `ng-non-bindable` correctly - add some more assertions to `TemplateCompiler` - make `CompiledTemplate` const - fix default value for `@Directive.moduleId` - add new compiler to application bindings BREAKING CHANGE: - `Compiler.compileInHost` and all methods of `DynamicComponentLoader` don’t take `Binding` any more, only `Type`s. This is in preparation for the new compiler which does not support this. Part of #3605 Closes #4346
