@hokein The problem with the non-type template case is that we would have to 
check the validity of constructs outside the potential _template-argument-list_ 
in order to disambiguate. For example, `w.x<y>::z` may be a valid expression 
(interpreted as `((w.x) < y) > ::z`) if the type of `w` is a class type that 
declares a member `x`, `::z` exists, and both `<` and `>` comparisons are 
valid.

@cor3ntin Yes, this is what I was thinking and is the resolution I prefer.
