This may be superceded by #352. But I've got a situation where I'd like to do something like:

select(df, known_col_name, starts_with("cluster_"), vector_of_col_names)

That doesn't currently work. It seems like select_q will be one approach. Another approach would be a special function along the lines of matches_any(vector_of_col_names), which would let me keep the bare word known_col_name.

The workaround's not difficult, but this'd be a nice to have. Thanks!

I like the function idea but I think the name is a bit imprecise. How about one_of?
