import as a means of code execution

[briandowns]

I was giving some thought about building another FaaS system for fun. After experimenting with a lot of different approaches I found that the import statement is a great means of code execution. There are another of other interesting approaches as well but wanted to brainstorm on this idea.

The roadblock I'm hitting is that the module is added to the vm->modules table. Another hinderance is that variables aren't able to be used as import targets.

I'm going to keep experimenting with different means of executing dynamically generated or provided code but wanted to get the conversation started around some of these things.

===========

even.du

print("even");

odd.du

print("odd");

while (true) {
        const val = Random.range(1, 1000000);
        if (val % 2 == 0) {
            System.sleep(2);
            import "even.du";
        } else {
            System.sleep(2);
            import "odd.du";
        }
}

or

while (true) {
        const val = Random.range(1, 1000000);
        var modName = "";

        if (val % 2 == 0) {
            System.sleep(2);
            modName = "even.du";
            import modName;
        } else {
            System.sleep(2);
            modName = "odd.du";
            import modName;
        }
}

Another option would be to provide an exec function like Python does.
