`await` is not importable because it's a keyword

[NullVoxPopuli]

Describe the bug

If I were to `import { await } from 'svelte/internal/client``,

I get a this error:

Unexpected reserved word 'await'. (1:9)

> 1 | import { await } from 'x';

or

 x `await` cannot be used as an identifier in an async context
   ,-[input.ts:1:1]
 1 | import { x as await } from 'x';
   :               ^^^^^

ESBuild's behavior is a little different:

What problem is this causing? Export names don't need to be valid identifier names.

This is valid tho:

import * as x from 'x';

x.await(node, get_input );

which.. is valid, but then I'm not sure how to re-export as named:
as this isn't valid:

export const { await } = x;

This sounds like a "how does javascript work?" question. There isn't a bug here.

[NullVoxPopuli]

I mean, I guess...

And since it's an internal module, I can accept you not wanting to do anything about it.

I'm building a Svelte REPL, and will have to pivot on how I'm doing the approach for this module.

I think you can do

export const await_block = x.await;

if you want to re-export as named (with a different name)...and then upon import you can rename it

right, but it's svelte itself that's using the import not me directly.
I'm using es-module-shims, which encourages intercepting modules via blobs, so I have a re-export thing with a cache on the window and then re-build the re-exports based on the keys from the value of that cache.

So..

const blobContent =
  `const mod = window[Symbol.for('${secretKey}')].resolves?.['${name}'];\n` +
  `\n\n` +
  `if (!mod) { throw new Error('Could not resolve \`${name}\`. Does the module exist? ( checked ${url} )') }` +
  `\n\n` +

  `${Object.keys(result)
    .filter(isNotKeyword)
    .map((exportName) => {
      if (exportName === 'default') {
        return `export default mod.default ?? mod;`;
      }

      return `export const ${exportName} = mod.${exportName};`;
    })
    .join('\n')}
      `;

const blob = new Blob(Array.from(blobContent), { type: mimeType });

which... I think I need to find another way to do this.

Not a huge deal -- just a fact of how things work. thanks!
