I wanted to generate a sequence of binary numbers so I tried code like:

print unpack ('B16', $_)."\n" for (0..10);

which generated:

00110000
00110001
00110010
00110011
00110100
00110101
00110110
00110111
00111000
00111001
0011000100110000

which is not what I expected! Where I expected that the for loop variable would be stored as a number, it seems to be being stored as a numeric string: '0'..'10'. Why is that? Is it possible to coerce Perl into storing a number as an integer in that sort of context?

Note that I have solved my initial problem using an sprintf, which may well be what I should have used in the first place.

Perl is Huffman encoded by design.
