Sure, but there is no way to avoid extending the Python parser and
then your DSL becomes external.

I remember having had a similar discussion a while ago with Kevin
Dangoor the original TurboGears developer who has also written Paver
[1]. In the end DSL syntax wasn't worth the hassle and Kevin developed
Paver entirely in Python.
