Ambiguous resolutions confuse people in general which was why I added 
the warning.
But I don't have a strong opinion on how useful this warning is; e.g. it 
warns people over declarations that look like constructor calls but it's 
not likely for people to write stuff like

T1(T2(x));

since creating an object like that isn't very useful.
If the consensus is that the warning doesn't add much value I'll remove it.

On another note, I find the function declarator ambiguous warning 
useful, since stuff like this:

T1 x(T2(y));

are more likely to occur and confuse people.
