###

#### abstract class TastyUniverse extends TastyCore with FlagOps with TypeOps with AnnotationOps with ContextOps with SymbolOps with NameOps with TreeOps

A facade to `scala.tools.nsc.symbtab.SymbolTable`, providing operations that map from the language of TASTy to the nsc compiler, e.g. to create trees, resolve types and symbols.

   Maintains state through traversal of a TASTy file, such as the outer scope of the defintion being traversed, the traversal mode, and the root owners and source path for the TASTy file. It also provides all operations for manipulation of the symbol table, such as creating/updating symbols and updating their types.

     (Since version 2.12.16) Use `formatString.format(value)` instead of `value.formatted(formatString)`, or use the `f""` string interpolator. In Java 15 and later, `formatted` resolves to the new method in String which has reversed parameters.
