~p format tries to write strings as strings, and since string is just
a list of small integers, it matches what you have there. In fact, 40
stands for '(', 42 is '*', and 91 is '['. You can check yourself:

What you want probably is to use ~w format, since it prints lists of
integers as just lists of integers.
