Leading comments in JS

[Ayc0]

Here there a way to have access to the leading comments on a variable / expression?

Like with the following code:

import { parse, plugins } from "@swc/core";

import VisitorDefault from "@swc/core/Visitor.js";

const { default: Visitor } = VisitorDefault;

class CustomVisitor extends Visitor {
	visitExportDeclaration(e) {
		// Can I gather e.leadingComments somehow?
		return e;
	}
}

const codeSample = `
// Foo
export const b = 'b';

`;

const visitorToPlugin = (visitor) => (m) => visitor.visitProgram(m);

const pluginsToApply = plugins([new CustomVisitor()].map(visitorToPlugin));

parse(codeSample, { comments: true })
	.then((_) => pluginsToApply(_))
	.then((_) => JSON.stringify(_, null, 2));

is it possible to have access to the leading comments when visiting the module with CustomVisitor#visitExportDeclaration?

Currently, it's not possible.
Adding apis for it would not be hard, though.
