It's easy to control that.

But to read it is awfull, don't think now, pay latter :-)

Not really a problem in practice, I have used both solutions and the
only way to have the this-> working is to ask the compiler where this is
needed, which is a long and painfull process. and then you can miss 
one if you have a global X. Using declaration only require a few 
compilations cycles.

Also, if this-> was not considered a visual nuissance, why limiting 
its use to  templates ?
