It was suggested that I make a post proposing syntax highlighting by tag.
This is based on a quick scan of tags by popularity. So the list is surely incomplete, but hopefully a good starting point.
It probably makes sense to be sparing with auto-highlighting (or at least start that way and increase it over time). For example, it's very common for people to have
go-ethereum questions that are not about go. It seems reasonable to expect people to also tag with
golang if they want go syntax highlighting.
I assume there is no syntax highlighting for solidity yet, so I skipped those.
