FWIW, the angry negative responses to removing parenthesis from the community would be a much bigger obstacle to adoption than the parenthesis. Nothing is going to turn me away from a technology faster than a hostile community, especially for a programming language, where the ecosystem is both an important asset and an investment you make when you choose a language to write in.

And I’m serious: I adopted Go early on for it’s ecosystem and community. Rust was harder in part due to its early negative reputation for overzealous fanatics, which thankfully no longer feels like an issue (and the ecosystem is getting there, too.)
