No, I was correct. Briefly, my question was "why is static typing good?" and the answer given was "static typing is good because it makes development easier." To the extent that "good" here just means "makes development easier" (and I think that is a lot of what "good" means in this context) then the answer I received was question begging to precisely that extent. Which is why I said "... to an extent." The conclusion was not quite assumed but a pretty similar conclusion was.

I can see how it appeared that I was using the phrase in the incorrect way! That usage bothers me too, and I am attentive to it.
