Compiler should not permit fields with function types and struct functions to share the same name

[tgschultz]

pub const S = struct
{
 func: fn() usize,
 
 pub fn func(self: *S) usize
 {
 return 2;
 }
};

pub fn func() usize
{
 return 1;
}

test ""
{
 var s = S{ .func = func, };
 debug.assert(s.func() == 2); //ambiguous
}

I think this is an important proposal, but deliberation and decision will have to wait until 0.5.0.
