…rsing the next token to see if it's also a DotToken. I see LanguageParser.IsAtDotToken accounting for about 1 second of CPU time (0.5%) in the C# editing speedometer test. Local testing indicates about 85% of calls into this method will be filtered by this check. Going to initiate a speedometer run via a tes insertion and will update with the results when available.

Speedometer results look good:
*** Old allocations under IsAtDotDotToken ***

*** Old CPU under IsAtDotDotToken ***

*** New allocations under IsAtDotDotToken ***

*** New CPU under IsAtDotDotToken ***
