964 used tables to look up the function to use, but
965 - if the table contains both assembler and disassembler functions then
966 the disassembler contains much of the assembler and vice-versa,
967 - there's a lot of inlining possibilities as things grow,
968 - using a switch statement avoids the function call overhead.
