I was just about to need that kind of library, the timing of this thread
is perfect for me.

I won't need it in my current project, but I noticed that struct,
contrary to lpack, doesn't have a way to capture a size_t sized integer.
On some platform, especially Windows x64, the long is 32bits only, while
the size_t is 64bits. It would be a nice addition to struct.

On the other hand, lpack has the opposite problem for size+string
matching. On Windows x64, 'p', 'P' and 'a' match a string with a
prefixed sized of respectively 8 (unsigned char), 16 (unsigned short)
and 64bits (size_t). It would be handy to have a string matching pattern
which uses 'unsigned int' as a size type.
