Do you want a "bind" or do you want to create a call expression?

About "bind":
The "bind" needs two language features, that are specific to JS: 
1. functions are objects
2. no type safety

The first would need pas2js support for typecasting a function to
TJSFunction.
The second needs an unsafe type cast from JSValue to whatever &then()
expects. Since you are missing any type safety anyway you can
simply use an asm block.


About creating a call expression:
Use a nested function or wait till anonymous methods are implemented.
