IMO, implicit slicing of static arrays ought to be killed with fire. This is not the first time it has caused problems. In the past it used to cause issues with the implicit slice escaping the scope of the original static array, leading to dangling pointers and subsequent memory corruption / UB. With -dip1000 the situation has somewhat improved, but not entirely. It still causes nasty surprises when a slice was implicitly taken where it was unexpected. This case here is another example of the problems that it causes. T -- I don't trust computers, I've spent too long programming to think that they can get anything right. -- James Miller
