Description

Take the following code as an example

source  = "const obj = { async* generator() {}};"
esprima.parseScript(source, { tolerant: true }))
code = escodegen.generate(ast);
console.log(code);

The output is:

const obj = {
    async,
    *generator() {
    }
};

Research direction

Start with the provided esprima.parseScript example and inspect the AST before escodegen.generate is called. Reproduce the async* generator object expression and trace where it is parsed as separate async and generator parts; done means the generated output preserves the async generator syntax.
