If there will be short names like "to" or "as" in the namespace then namespace qualification in user 
code will practically be necessary. So 'convert' would look much better in that case. But I'm not a 
fan of the short names and would rather do:
namespace bcv = boost::conversion;
bcv::convert_to<int>("42");

On the other hand, 'convert' is both a noun and a verb. :P

I agree with Rob; the word "or" is a bad way to end an identifier.
