Yes, they are in the global scope, and from what I gather: they are just regular functions, created by special syntax.<br><br>There are a few obvious solutions (some of which you might have thought yourself :-):<br> - rename the accessor or the other function, or<br>
- put the data declaration or the other function in another module and import qualified, or<br> - write a typeclass with a 'name' function and fit the non-accessor function 'name' somehow into that...<br>
