I believe you can do this with:
switch (pc++)
and there are the same number of indirections.
And how is pc is supposed to be an opcode? It's a counter after all...
switch (pc++)
and
goto code[pc++]
are the same (same as in same number of indirections).
switch (code[pc++])
and
goto code[pc++]()
are the same, too.
