It isn't a goal of Converge to be Pythonic as such (particularly as Python 2.x is a philosophically different beast to Python 1.4/1.5-ish).
My impression of Boo is that its macros are a very different kettle of fish to Converge's compile-time meta-programming. Boo seems much more similar to Nemerle than Converge. As far as I can tell, there's no quasi-quoting (which would mean building ASTs by hand all the time) and no support for things like hygiene. I'd be happy to be corrected though.
Pre 0.8.1 there was no backtick and it was all manual AST afaict. 0.8.1 has [| |] which is similar to ` I believe. See second link above. Not sure about hygiene though, I guess not.
