      Returns:
        true if this method is the run method from a script

    - #### setIsScriptBody

          public void setIsScriptBody()

      Set the metadata flag for this method to indicate that it is a script body implementation.
      See Also:
        `createStatementsClass().`

      Indicates that this method has been "promoted" to public by Groovy when in fact there was no public modifier explicitly in the source code. I.e. it remembers that it has applied Groovy's "public methods by default" rule. This property is typically only of interest to AST transform writers.
      Returns:
        true if this class is public but had no explicit public modifier

    - #### setSyntheticPublic

          public void setSyntheticPublic​(boolean syntheticPublic)

      Provides a nicely formatted string of the method definition. For simplicity, generic types on some of the elements are not displayed.
      Overrides:
        `getText` in class `ASTNode`
      Returns:
        string form of node with some generic elements suppressed
