compare v8 and SM results

[redchair123]

there should be a syntax (e.g. c> ...) that will run a command in both SM and in v8 to compare the results.

For example, I want to highlight something that SM supports but not v8:

>> var [x,y] = [1,2]; print(x,y)
>>> var [x,y] = [1,2]; console.log(x,y)

I'm not sure I quite understand the purpose. What do you want the output to be, ideally?

I think the point is to run one command and see the output in both v8 and sm so that you could compare the results. For example, v8 currently doesn't support destructuring and thus would fail.
So running

c> var x,y; [x, y] = [1,2]; console.log(x, y);

we would see

v8> Syntax Error
sm> 1, 2

Very well. I'll make sure to implement something like this soon.

though, would still be funnier if the trigger was >>>>> rather than c>

it would have been cute. alas.
