This is a known issue, it's because there is an ambiguity in c++, that there 
_could_ be a template class called "column" with the arguments inside the <>.

I emailed Roberto about it a while back but his suggestions are technically 
difficult at the moment, it will need more thinking about before we can 
properly fix it.
