Assignment operator meaning
For class types, this is a special member function, described in copy assignment operator.
Assignment Operator := - Analytica Wiki
For class types, this is a special member function, described in move assignment operator. For non-class types, copy and move assignment are indistinguishable and are referred to as direct assignment. For the assignment operator meaning operator, lhs may have any non-const scalar type and rhs must be continue reading convertible to the type of lhs.
For assignment operator meaning types, the right operand is first implicitly converted to the assignment operator meaning type of the left operand, and then its value is copied into the object identified by left operand.
When the left operand has reference type, the assignment operator modifies the referred-to meaning. If meaning left assignment operator the right operands identify overlapping objects, the behavior is undefined unless the overlap is exact and the type is the same.

For a type to be CopyAssignable , it must have a public copy assignment operator. The copy assignment operator is called whenever selected by overload resolution , e.

Analytica doesn't allow assignment to global variables, except in a few special cases. This comes as a shock to many experienced programmers because assignment is perhaps the most common operation in conventional computer languages. But there is a good reason to avoid assignment.

The result of an assignment expression is the value assigned to the left-hand operand. The type of the right-hand operand must be the same as the type of the left-hand operand or implicitly convertible to it.
