Code detection is flaky when you define helpers for `inSpan`

[parsonsmatt]

If you define an inSpan helper function like:

myInSpan :: HasCallStack => Text -> IO a -> IO a
myInSpan name action = inSpan name defaultSpanArguments action

Then every use of myInSpan will be registered as the function that the span originates in. This is because inSpan' uses callerAttributes which only cares about the caller of inSpan.
