    args = performTransaction.Arguments
    return [|
        _transaction = $(args[0]).BeginTransaction()
        try:
            $(performTransaction.Block)
            _transaction.Commit()
        except:
            _transaction.Revert()
            raise
        ensure:
            _transaction.End()

Have you looked at the implementation in Nemerele?

Personally, I like the way macros are written now. While they are a
little harder to write, they are easier to read. Plus, the more
easier macros is to create, the more they will be abused. I've seen
C++ code that does not look like C++ anymore due to macro abuse.

I don't think a feature should be harder than necessary, just to keep people from using it ...for a counterexample, look at Lisp (and Scheme), where macros are used almost as much as functions, and everything works out great.
