How do I create a set type in v?

[mark-summerfield]

I want to create a set type that holds strings. At the moment I'm using map[string]bool but I only care about the key and don't need values. Is this possible in v? (I don't want to implement sets from scratch.) What I need is fast membership testing and fast add/remove; ordering doesn't matter.

I don't know if it would be "fast" enough for you, but you could just create a string array and use the in operator to test for existence.

The set of words will have approx 4000 words in it and a linear search isn't good enough. I want a set or failing that a hash/dict/map.
