Duplicate titles are now plain forbidden. I do think that it's a good thing in most instances. But a blanket ban like this is annoying sometimes.
Case in point:
“Perfect” here means that I wanted to use user B's title on user A's question. Question A had answers while question B didn't, so I voted to close question B as a duplicate of A and not the other way round, even though question B was better worded overall. (Merging isn't an attractive option, the questions are similar enough to have similar solutions but have different example data.)
My edit to give question A the title of question B was not accepted due to the title duplication. I had no reason to edit question B, and every reason. What I ended up doing was a minor grammatical variation on the title. Is this the best we can do?
