// UPDATE: In 2023, you should probably stop using this! The narrow version of Safari that
// does not support `nomodule` is probably not being used anywhere. The code below is left
// for posterity.

/**
 * Safari 10.1 supports modules, but does not support the `nomodule` attribute - it will
 * load <script nomodule> anyway. This snippet solve this problem, but only for script
 * tags that load external code, e.g.: <script nomodule src="nomodule.js"></script>
 *
 * Again: this will **not** prevent inline script, e.g.:

Everything mentioned here is work in progress. It is not sure that these ideas will work out:

• They may break the web.
• They may turn out to be too complicated/user-unfriendly.
