It depends on how long the names in the C code can be, and whether one
want the names in the object code to be the same as the names in the
source code.


One could choose Z as an escape character, and have ZZ mean Z, ZD mean
".", ZC mean ":", ZP mean "$", ZA mean "@", etc. Tough on names with
Z's in them; let's hope there aren't that many.
