Rather than a new scheme, a simple and effective approach is to compress using 
lzw. Lzw is nicely reversible, too, though the symbols will look like tty noise 
in the linker maps and the debugger.

One approach is to lzw them only if they exceed a certain length, and to leave a 
prefix that makes some sense to the user, like the function name.
