Import via esm.sh failure

[vasturiano]

First of all, thanks for this awesome module!

When I try to import taichi.js in the browser, bundled with esm.sh, as simply as:

<script type="module">
  import * as ti from 'https://esm.sh/taichi.js';
</script>

I get the following error:

Uncaught TypeError: R.platform is not a function
    at taichi.js:16:126746
    at taichi.js:16:133807
    at taichi.js:16:134044
    at taichi.js:16:3206224

Would you happen to know why? I'm not sure if this is an issue on esm.sh or if there's some config that I might need to apply in the bundling to solve the error.

Thanks in advance!
