Setting Variable Values

`Assignment` Type

A non-overloaded binary assignment operation, including =, +=, &=, etc. - Assignment

A non-overloaded assignment operation with the operator =. - AssignExpr

This is an AssignExpr:

a = b;

This is not an AssignExpr (but it is an Assignment):

a += b;

This is an Initializer, not an Assignment:

int i = 1;

This is a VariableAccess, not an Assignment:

i++;

This is also a VariableAccess, but the isModified() predicate doesn't hold:

return i == 0;
