This command doesn't attempt to assign x=3.
The equals sign is not only an assignment operator, it is also a
comparison operator.
Try this:
atom x
x=5
?x=6
?x=5
The first will print zero (false), because x is NOT equal to 6. The
next one will print one (true), because x IS equal to 5.
It is completely legal to use comparison operators in an expression
this way.
