Do we have such a mechanism with Python ?

The tal:importfuture statement is enough I think: an old parser would not 
know about it. We may need to ensure that it is playing well with macros. 
IOW What if a page parsed by an old parser uses macro defined in a page 
with the tal:importfuture statetement. Do we need a correlated 
metal:importfuture ?
