Does std.regex support input ranges to match()? Or do I need to convert
to string first?

Thanks!

For now, yes you have to convert them. Any random access range of code units should do the trick but stringish template constraints might kill that.

I plan to extend this eventually. The problematic point is that match internally is delimited by integer offsets (indices). Forward ranges technically can work (the match then will return something like take(..., n);) with a bunch of extra .save calls. Input ranges can't be used at all.

Is there any progress on this thing?
