> I don't think IDEs do a lot of parsing to do syntax highlighting, isn't it all just regex matching to identify the types of tokens?

IntelliJ highlights variables etc. differently if they're unused and can highlight different identifiers in different colors. Not sure about other current IDEs.

That said I never felt like I needed such features, normal syntax highlighting does the job pretty well for me.

IntelliJ has context-aware autocomplete. Type this.field.get and it will show methods and fields starting with get for whatever type field is. There's a lot of context needed to make that happen.
