Bug 17247 – std.bitmanip.read should not assume sliceable range is assign-copyable to ubyte[].

std.bitmanip.read wrongly assumes that if an input range has elements that are implicitly convertible to const(ubyte), and it supports slicing operations, then it is possible to copy range elements to a ubyte[] static array using the assignment operator. Obviously this only works if the range is ubyte[] or a similar built-in type, but it fails horribly for user-defined ubyte ranges that support slicing.

In other words, std.bitmanip.read should not assume that slicing a ubyte range will return ubyte[] or similar, since it could be a user-defined type.
