I'm not saying that it can't be done. I'm just saying that all of the corner 
cases and the like have to be sorted out such that the feature is completely 
defined, and we don't have ambiguities that are going to cause problems. Things 
are complicated enough with alias this and opDispatch and the like. Adding yet 
another way to add functions to a type complicates things that much further. 
So, UFCS needs to be carefully designed, and that's more of an issue IMHO than 
the exact syntax used to determine if a function is supposed to work with 
UFCS.
