* Assignment is an abstraction of assignment.
|
|
* It is different from i.e BasicExpression so that it change value of the lvalue
|
|
* and has to forward this change to whole system. Assignment does it thanks to its
|
|
* fellowship with right context
|
|
* if expression is assigned not to variable, it doesn't update value of variable of course
|
|
* it just gives value of rvalue...
|
|
* mmm... maybe it'd be better to return InvalidExpression with appropriate error message such
|
|
* as: "Invalid assignment, values cannot be assigned to constant values"
