joo_global_object is undefined when bundled in strict mode

[copy]

jsoo uses this compilation scheme to detect the global object:

(function(joo_global_object)
   {"use strict";
       console.log(joo_global_object);
       // ...
   }
  (function(){return this}()));

This fails when the generated JavaScript is bundled together with other JavaScript files that have a global "use strict"; stanza, as this doesn't become the global object in strict mode.

You can compile with --wrapWithFun flag and initialize the script yourself

Good point, that's what I'll do.

Still would be nice to have it working within jsoo, for example using Function("return this")().

Where did you find the Function("return this")() solution ?

Any update on this? This is still an issue since #710 is reverted.

Quick survey shows that you can use an arbitrary variable as joo_global_object if you pass `Custom "some_name" to ~global: https://github.com/ocsigen/js_of_ocaml/blob/master/compiler/lib/driver.ml#L370

But there is no command line option to do that: https://github.com/ocsigen/js_of_ocaml/blob/master/compiler/bin-js_of_ocaml/compile.ml#L56-L59

I just ran into this issue due to some misconfiguration on the html file that was loading the jsoo bundle with <script type="module" .. /> attribute. And apparently modules use strict mode automatically.

Is there anything preventing jsoo to use globalThis instead of this? Browser support seems to be quite good, and oldest Node version supported is 12, which is already in maintenance LTS.
