                                a with
| _ -> ()

match! // foo!
                                a with
| _ -> ()

Result

match a with
| _ -> ()

match! a with
| _ -> ()

Problem description

The is no TriviaNodeAssigner anchor node to connect the trivia comment.
I do notice that the SynExpr.Match (and MatchBang) starts from the match keyword, so a node could be constructed from this information in ASTTransformer.

Extra information

• The formatted result breaks by code.
• The formatted result gives compiler warnings.
• I or my company would be willing to help fix this.
