It seems like it should be straight forward to write Bytes to a File.
outy = Array(UInt8).new File.open("abc", "w").write(outy)
But it yields this:
Error: expected argument #1 to 'File#write' to be Slice(UInt8), not Array(UInt8)
Apparently requiring some extra work (and magic) to use. There is also a write_bytes method but it also yields
Error: undefined method 'to_io' for Array(UInt8)
Might be nice to make this easier. Cheers!
