The problem is that you are using ~ with an uninitialized Buf/Blob
my Buf $read;
$read ~ Buf.new;
# Use of uninitialized value element of type Buf in string context.
Note that it is not complaining about it being a Buf. It is complaining
about it being uninitialized.
If you initialize it then it works just fine.
my Buf $read .= new;
$read ~ Buf.new;
It will also work with ~=
my Buf $read .= new;
$read ~= Buf.new( 'a'.ord, 'b'.ord );
$read ~= Blob.new( 'c'.ord, 'd'.ord );
say $read.decode; # abcd
It also works with Blob, but you may not want to do that if you plan on
modifying the contents with something like `.subbuf-rw()`.
