No!

DR 152 is about what happens when you pass an argument by value and
the copy-constructor happens to be explicit.  DR 152 says that well,
you loose -- the copy-constructor is a converting constructor and if
it is explicit, then the pass-by-value fails.  Read the last sentence
of bullet 1 and bullet 2 carefully.

It is exactly the opposite.  DR 152 is a distraction.
The PR is about 

| DR 152 is TR1

if it were TR1, it would not have been the C++ standard.  It is TC1,
but again this issue is NOT about DR 152.  It is about DR 391 and
and related aspect.
