ngcc would feed ngtsc with the function declaration inside of an IIFE as that is considered the class symbol's declaration node, according to TypeScript's `ts.Symbol.valueDeclaration`. ngtsc however only considered variable decls and actual class decls as potential class declarations, so given the function declaration node it would fail to generate the `setClassMetadata` call. ngtsc no longer makes its own assumptions about what classes look like, but always asks the reflection host to yield this kind of information.

Angular Compatibility Compiler (ngcc)
This compiler will convert node_modules
compiled with ngc
, into node_modules
which
appear to have been compiled with ngtsc
.
This conversion will allow such "legacy" packages to be used by the Ivy rendering engine.
