Warn about gotcha in #1152
Warn when using unsupported mix of send and field
I have no real opinion on this but would console.warn be slightly more semantically correct if we consider these "warnings"? I think ultimately this is going to cause misbehavior so they usually do represent actual errors in the application needing a code change to fix. (In which case console.error seems like the best choice)
I have no strong opinion either way. I went withconsole.error, because it may become an error.
