[C++-sig] Limits of implicitly_convertible?

[Hans Meine]

Hi!

I could not get implicitly_convertible<list, MyVector>() to work *at all*, so 
I tried the example from the documentation.  (BTW: My compiler told me that 
operator int() had to be const, that should probably be fixed in the docs.)  
That simple example worked, but when I changed the constructor to take a list 
instead of an int, it ceased working.  Attached you'll find a minimal 
testcase.
