I request the feature of syntax highlighting Assembly and Basic code. As W5VO said, we don't have it yet. However, Assembly is used regularly on this site. And while we're at it, why not add Basic as well?
Both languages aren't included in the standard Google-Prettify package. However, there's an extension for Basic.
There isn't an Assembly extension yet, but perhaps it can be made by the team? It would make already obfuscated (because of being assembly) code better readable.
