I may seem to cut hairs in four parts (as we say in French: "Couper des
cheveux en quatre"), by the length of course, but shaving bytecodes can be quite
hairy...
Sorry, I couldn't resist for the (bad) pun. I just come out of the
haircutter...

OK, more seriously, you are quite right.
Now, if this idea have some success, it can be necessary, some day, to break
the file in parts. A generic one, that can be used by various functions, a
file I/O one, a string one, an encoding/decoding one, etc.

Perhaps a generic file will load the required libraries, based on a table,
in a similar idea to Luiz' one.

I am not sure if it is a good idea: how to break down the file? What about
dependencies, as you indicate? We can force a dofile to be sure to have
required functions, but I wonder what happens if a.lua has a dofile("b.lua") and
b.lua has a dofile("a.lua")...
Anyway, the idea of loading a 100KB file to be able to dump a table for
debugging isn't so terrific either...

I can always cut/paste the code, but:
1) It will be frozen, ie. updates are quite hard to do, even more if used in
several scripts. At least, we can be sure it won't be broken by a hazardous
change...
2) We lose the interest of such a file, where we just have to type a line to
get a much used functionality.

Regards.
