~I just switched over to mapset from using a home grown set implementation, and really enjoying mapset. This functionality is the only aspect missing. @deckarep any chance this may be looked at for inclusion?~

Disregard -- I didn't realize that NewSet allowed for variadic values to be specified. Fantastic. Nice work @deckarep!

I should have some time to look at it later today.

Thanks for the interest!

@SignorMercurio - Hello, looks like this PR has merge conflicts after I merged a few PRs. Do you have any bandwidth to tackle them? I'm still swamped currently but will get to it eventually. I appreciate your contribution!

[SignorMercurio]

@deckarep Sure, I've resolved conflicts now.

[deckarep]

@SignorMercurio - hmm still seeing conflicts unfortunately. I am unable to merge.

@deckarep I'm not sure why I cannot see the conflicts now:

Is there anything I can do to help?

@deckarep I'd love to avoid for loops for adding multiple values to a set. Would you have time soon to merge this PR?
