Bug description

the issue with ID 0004941
"Physical equality is a very subtle beast." - ertai

One should not have to experiment to determine semantics.

Under what conditions physical equality holds is not wholly documented except for objects and it is incongruous that object equality uses (=) not (==) even though (==) is the physical equality operator and "Two objects are equal if and only if they are physically equal. In particular, an object and its copy are not equal."

Additional information

Quick fix, from Pervasives.html
"On mutable structures, e1 == e2 is true if and only if physical modification of e1 also affects e2."
should be changed to
"On mutable structures, if e1 == e2 is true, physical modification of e1 also affects e2."

This way A-->B rather than the current A<-->B.
<-- = --> = "implies"
