.first throws an error if used with less than 2 values

[renatoargh]

I have a dinamically set array of env variables which I pass to .first. Having this limitation makes me check for the length of the array and use .get if there is only a single element.

What is the reason behind this limitation? Is it something that we stop throwing this error, or at least make it configurable?

PS.: thanks for your awesome lib 👍

Ah, that's an interesting use case I didn't consider. Yes, the idea was that if you were using first() with a single-item array, that it was probably an error and you should be alerted.

I can see an argument this case isn't important enough to throw an error because there is really no harm done with a one-item array. I'm not opposed to changing this behavior.

If it is fine for you then I will try to come up with a PR soon (not sure when though). In the meanwhile I will keep my ifs :)

I'm on it. 👍
