The reason to have that 'if not binary_file' check, was to avoid
dumping massive amounts of binary data on your screen if you happen to
type foo?? where 'foo' is some arbitrary foo.so extension module.
This happened several times to users, and since binary dumps in a
terminal often end up corrupting the terminal state itself (the
teminal interprets them as control codes), this is a Bad Thing (TM).
But I realize that your pyrex-generated files will provide
'reasonable' information when queried, which is why you want to
actually open them. Is there any way we can distinguish your files
from non-pyrex, non-docstring-enhanced binary extensions? I want to
provide access to the pyrex embedded info, but at the same time
protect the users from terminal corruption from other binary libs.
A last resort solution can be to analyze the returned string and try
to guess that it's binary from the presence of high-order bits in it,
but I'd like to know if your pyrex conventions provide a simpler
solution.
