 #### Setter Bypass
 
-It is important to know that when you initialize a field with `options.bypass` set to true, existing setters will by bypassed. That's particularly helpful if your setter triggers a side effect that you don't want triggered. This is achieved by generating the assignment as `(untyped this).$name = $value`. To make the code typesafe again, this is prefixed with `if (false) { var __tmp = this.$name; __tmp = $value; }`. This code is later thrown out by the compiler. Its role is to ensure type safety without interfering with the normal typing order.

 Setter bypass also causes the field to gain an `@:isVar`. And currently, with `-dce full`, additional code will be generated to avoid the field to be eliminated.
