> I wish there were more posts where people impliment an application with multiple tool sets and compare them, give insight into what some things are good for and not. "Tool Benchmarking" might be a good term for it.

I recently started working on a project like this. It's hard work.

Building a complete tool in one language takes a long time. Not to mention 2, or 5.

Moreover, many (most?) programmers are only "fluent" in one or two languages. Even if you "know" a language, you might not know the full build toolchain, or you might not know common idioms, etc.

Most people probably want to work on building new/interesting/fun stuff, not reimplementing the same toy program in several different languages.
