Note:
(1) Like dis.disco, the argument is not a FUNCTION, but the function's
"func_code" attribute/member. Call it as "disco( func.func_code )."
(2) Since it want's to look up the source code with linecache, it
will fail if it is 'compile()'-ed code from an internal string,
or it linecache can't find the file on sys.path.
Try this on your favorite Python function to see what Python byte-code
"assembler" looks like!
