   - serializes standard library AST using serde

+  - used by default
 - none
   - leaves only stdlib source code in binary, processing them same way as user supplied data
   - slowest (as it involves parsing of standard library source code)

-Because of `codegenerated-stdlib` compilation slowdown, `serialized-stdlib` is used by default
