That's because list_to_binary/1 is defined to take an "iolist",
which is a tree structure whose leaves are binaries and *bytes*,
flatten it, and give you a binary. Had you tried a larger integer,
such as list_to_binary(), you would have had even more trouble.
What you want is term_to_binary/1 to do the encoding
and binary_to_term/1 to do the decoding.
Searching the 'erlang' manual page for 'to_binary' and 'binary_to'
would have found these.
