For years, XEmacs has had functions for accessing parts of
byte-compiled code.  It would be great if Emacs had some equivalents.
Below is the documentation on those functions from the XEmacs Lisp Manual:

The following primitives are provided for accessing the elements of a
compiled-function object.

Function: compiled-function-arglist function
  This function returns the argument list of compiled-function object function.

Function: compiled-function-instructions function
  This function returns a string describing the byte-code instructions
of compiled-function object function.

Function: compiled-function-constants function
  This function returns the vector of Lisp objects referenced by
compiled-function object function.

Function: compiled-function-stack-depth function
  This function returns the maximum stack size needed by
compiled-function object function.

Function: compiled-function-doc-string function
  This function returns the doc string of compiled-function object
function, if available.

Function: compiled-function-interactive function
  This function returns the interactive spec of compiled-function
object function, if any. The return value is nil or a two-element
list, the first element of which is the symbol interactive and the
second element is the interactive spec (a string or Lisp form).

Function: compiled-function-domain function
  This function returns the domain of compiled-function object
function, if any. The result will be a string or nil.
