Description
I didn't find a way to directly construct fixed sized cpp_int from existing binary data (a static array, for example an RSA key hardcoded into a .cpp after being generated with OpenSSL)... I had to resort to either using the from-string constructor or inserting the data byte by byte with 8 bit shifts and or-ing in a loop both of which are ugly and inefficient (https://svn.boost.org/trac/boost/ticket/9233, https://svn.boost.org/trac/boost/ticket/9234)...
Ideally it would be possible to create static fixed size numbers as one creates PODs, without a dynamic initializer being created by the compiler..
