Regarding "Optimize Globally"

At my current job we generally use LINQpad for scripting, and have a lot of tests that use LINQPad scripts.

When I joined, there was a test that relied on an "R" script. Now, "R" might be the best tool for the job, but no one running the test would ever have any "R" experience. In addition, the environment to run "R" has quite the learning curve.

I ported the script to LINQPad. The fact that no one needs to install "R" or figure out how to run "R" is a much more massive timesaver than the fact that "R" was technically better for that one task. (And the script itself is pretty straightforward.)
