1. It complicates the compiler.
2. It slows down the compilation.
3. We didn’t think about it in the beginning, and can’t add it now without making non backwards compatible changes.
4. It makes the language harder to learn.
5. We don’t use this feature a lot.
I didn’t invent these reasons — search for why doesn’t golang have <insert-feature> — and you will eventually come across one or the other as a reason mentioned by one of the core members.
I get that you're just the messenger, but almost every one of these arguments makes my blood boil.
1. So what? The whole point of writing a high-level language is to pay the cost of low-level burdens once so that application developers don't have to pay them repeatedly.
3. This makes me treasure even more greatly the Rust core team's forethought when releasing Rust 1.0, in ensuring they hadn't walled themselves into any easily-avoidable corners before stabilizing the language. Such an approach has repeatedly paid dividends.
4. Optimizing for a person's first week of using a language at the expense of their next ten years is borderline indefensible.
5. This last one pretty much boils down the entire problem for me. Go is designed to solve problems Google has that most of us don't. It's also designed to solve them in a way that makes the most sense to Google (e.g., dependency management is irrelevant if you have a monorepo).
I totally agree, in case it wasn’t clear. Go, like many others, was designed by people who thought the users of the language are not as smart as themselves. They seem to have forgotten that after writing a few thousand lines, even a novice can become a power user and start demanding more of the language.
