TEST_OUTPUT:
---
fail_compilation/fail13435.d(22): Error: cannot implicitly convert expression `d` of type `int[]` to `S!int`
fail_compilation/fail13435.d(22):        `this._a = d` is the first assignment of `this._a` therefore it represents its initialization
fail_compilation/fail13435.d(22):        `opAssign` methods are not used for initialization, but for subsequent assignments
