Yes, this. And exception handling in the scripting language of
errors returned by the C library.
Earlier versions of M2Crypto had a "Blob" type that got
munched by Swig into the right Python thingy. It had this because
I had a vain goal of generating bindings for >1 language (originally
Python, Perl and Tcl) from one set of Swig files.
The most recent release of M2Crypto deprecated Blobs and used
Python objects directly in many places, because after writing
Python I am no longer inclined to write Perl and I've never gotten
around to Tcl. ;-)
This makes the current release of M2Crypto not useful for binding
to other scripting languages.
I've had a change of mind, though, so the next release of M2Crypto
might see some Blobs coming back in. I hope to handle Jython, a
Java implementation of Python, and I've also been looking at Lua.
Happy hols!
