not sure why we need two calls here. getGoToDefinitionAndBoundSpan subsumes the other one, so would be sufficient to do here.

i would say always use getGoToDefinitionAndBoundSpan and check the span only if the marker name was provided.

testName [](start = 16, length = 8)

It seems like this is actually the name of the API under test. #Closed

Which one is reported when the argument is undefined? Does it matter?

The argument is not going to be undefined only the response from the argument function. It happens when the token doesn't contain a definition.

I notice that the regular Definition command has a separate Full version. Does the new command need one as well? #Closed

Offline, I think we established that VS Code will probably not consume the new API. If this API is just for VS, should it have "Full" in the name? I think that's how we usually distinguish.

Based on a discussion with @mhegazy, I have added the method for the simplified, hence, the "full" has been updated.
