 That ought to be enough examples to be getting on with.
 .SS Implementation
-The symbol table is an extensible hashtable, using a 32-bit CRC as the
-hash function.  The hash chains are kept very short (probably too short,
-actually).  Every time a symbol is found, its block is promoted to the
-front of its bin chain so it gets found faster next time.
