Of course. My general approach for serialization is hosted here in a git
repository:
https://bitbucket.org/sils1297/serialization-test

A patch for octave is appended to this email. Please do not judge me by
this code, it was meant to be an experiment.

If you patch your version of octave with this patch, create a directory
named "tmp" and execute octave in the parent directory of tmp, the
version will save a serialized version of every statement to tmp/tmpA
(B, C, ...). You will find an example execution below my signature.

Serialization should work with comments (and nothing else). I did not
test deserialization with octave yet.

Greetings,

Example:
~/prog/octave/build$ ./run-octave --no-gui
octave:1> x=1 # a comment!
tmp/tmpA
x =  1
octave:2> exit
tmp/tmpB

~/prog/octave/build$ cd tmp 
~/prog/octave/build/tmp$ hexdump -c tmpA
