First of all, don’t ask me why I want to do this 
It was an experiment I was trying. I since decided to do it a different way, but it got me curious.
In the shell (or any other process for that matter), given a string like "time = System.os_time()" I can evaluate it with Code.eval_string("time = System.os_time()") and get back {1628697855326337000, [time: 1628697855326337000]}.
Yes, I know I can copy/paste the thing too, but humor me.
Is there a way I can programmatically inject the variable time into the shell’s variable bindings?
Basically do something like:
iex(1)> MagicModule.magic_function("time = System.os_time()")
1628697855326337000
iex(2)> time
1628697855326337000
iex(3)>
Where Next?

I found a really hacky way to do it in the shell
