Shorter, and much more readable, I'd say:
my Blob $blob = blob-from-carray($ed.data, size=>$ed.data_size);
say "bindata = { now - INIT now }";
The term "now" is short for "DateTime.now.Instant"
The INIT phaser is run when the program is started: it returns the value that was obtained from the code then executed.
Phasers for the win!
