I find "\xXX\xXX\xXX\xXX..." notation for binary data totally unreadable. Everybody who uses and analyses binary data is more familiar with plain hex dumps in the form of "XX XX XX XX...".
I wonder if it is possible to introduce an effective binary string type that will be represented as h"XX XX XX" in language syntax? It will be much easier to analyze printed binary data and copy/paste such data as-is from hex editors/views.
