Seeing the following in a binlog:

Looks like this is a very simple analyzer, but is somewhat slow. The analyzer registers symbol actions for named types, methods, fields, properties, and events.

So I assume this is alone too much work.

The analyzer should use IAttributeOperation when it's added back (but the analyzer will not work for people consuming a compiler without this IOp), or register a syntax action for AttributeSyntax.

Yes we try to avoid syntax analysis in many cases, but I think for this one we might see a good performance gain.
