            Bug ID: 193530
           Summary: [webkit2gtk][JavaScriptCore glib] typeof "API created
                    function" == "string"
           Product: WebKit
           Version: WebKit Local Build
          Hardware: PC
                OS: Linux
            Status: NEW
          Keywords: Gtk
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore

I'm trying to use the JavaScriptCore glib API to define some native functions for use in user scripts, they work great so far, but somehow the js user script typeof doesn't recognize them as "function".
For example:

/* web-extension.c */
static void

static void
windowobjectcleared(WebKitScriptWorld *w, WebKitWebPage *wp, WebKitFrame *frame,
                    gpointer unused)
        JSCContext *ctx;

        ctx = webkit_frame_get_js_context_for_script_world(frame, w);
        jsc_context_set_value(ctx, "zzz", jsc_value_new_function(
          ctx, "zzz", (GCallback)zzz, NULL, NULL, G_TYPE_NONE, 0));

/* user-script.js */
console.log(typeof 'zzz');      /* logs string instead of function */
console.log(zzz);               /* function zzz() { [native code] } */
