I don't think this is a good idea.  Generic code could result in an error  
where there shouldn't be.  For example:

int foo(T)()
{
    if(T.sizeof == char.sizeof)
      ...
}

Would this fail to compile where T == char?  What about if T == ubyte?

Generic programming sometimes results in silly code that is perfectly  
acceptable as generic code, and we need to take this into account before  
making decisions assuming a person is writing the code.
