Member expression on number literal generates wrong output

require("escodegen").generate({
            "type": "ExpressionStatement",
            "expression": {
                "type": "MemberExpression",
                "computed": false,
                "object": {
                    "type": "Literal",
                    "value": 4,
                    "raw": "4"
                },
                "property": {
                    "type": "Identifier",
                    "name": "foo"
                }
            }
        })
// => '4..foo;'

While it should output:

(4).foo;

Ah, I think I see what you mean. Thanks, @dannycochran. The fix here would be to compile to

4 .foo;

@dannycochran I disagree. Those should be identical in an AST. The fact that they’re not due to raw on Literal is the problem.
