There were some good questions brought up at the meeting.

How does the compile transform string interpolations?

How does the performance of string interpolation compare to alternatives?

Thanks, Dave!

I'm confused about the benchmarks. In the first benchmark, adding to strings and format were within a factor of 2 or so, but string interpolation was an order of magnitude slower. In the second benchmark, addition and interpolation were within a factor of 3, and format was an order of magnitude slower. Am I reading that right?

For the first benchmark, yes. For the second, I'm reading string interpolation to be about two orders of magnitude slower (you might have been looking at the GC time) while format is roughly 3 orders of magnitude worse (microseconds vs nanoseconds for that one; sneaky little mu). I haven't looked into the reasons behind the behavior yet. Perhaps someone on the list has some familiarly.
