I think that it is possible to write a metaprogram that will take a general 
expression tree and reparse it assuming whatever precedece you like.
This is not easily done, though. I actually think that we need some 
metalanguage, most likely functional, which will be mapped to template
metaprograms. But this is not  easily done as well.
