While reading Practical English Usage by Michael Swan, I found (p. 270, inversion section) that:
In spoken American English, exclamations often have the same form as ordinary (non-negative) questions (but with different intonation).
Have you got a surprise coming!
Is it valid if, instead, I make an exclamation with this following style?
Do you have a surprise coming!
Or are there certain ‘question-styled’ exclamations that are considered as legitimate while others just don't? What do you think?
