I find myself writing .iter().map(|x| ...).collect() really often in Rust. I'm wondering if I should write a helper method on Vec, but it seems less idiomatic. Iterators compose, but they're less versatile (no indexing) and awkward to return from functions.

Being able to choose your target browsers in Babel is a little like -march in a native code compiler! Browser targeting has the nice property that you can collect popularity metrics to make quantitative decisions too.

One thing data science has taught me is that I measure too rarely, collect too few samples and graph too rarely.
