Another way to do this could be to just create your own method.
my method decode-c(Blob:) { self.subbuf(^self.first(0,:kv)[0]).decode }
my $string-with-zero = Buf.new: 72, 101, 108, 108, 111, 0, 32, 119,
111, 114, 108, 100, 33;
say $string-with-zero.decode;
say $string-with-zero.&decode-c;
The output of the last two lines would be "Hello World!" and "Hello",
respectively (although with a U+0000 character after the first o). If
used frequently enough (or one dislikes the .& syntax), it could also
be added into Blob/Buf via an augment.
