Fix infinite loop using custom execution closure class

[setkyar]

I am fixing the ExecutionLoopClosure class's infinite loop causing a timeout.

Fixes #49

This is a lot of code to maintain. Isn't there a simpler solution? The package at some point did work correctly without that heavy class.

Hi @freekmurze, thanks for the comment. Firstly, my idea was stuck with the existing code. I checked how Tinker does and turns out we can use execute directly.

Did you verify in the browser that this fixed the problem?

@freekmurze I tested in the browser. It's fixed the problem.
