This has been discussed several times in the mailing list. The SI:BYTECODES
shows that the backtrace is made of toplevel bytecode forms. You can inspect
these forms. Type :help in the debugger and you will se that these three
operators do what you expect

:d(isassemble)    Disassemble current function.
:l(ambda-)e(expression)    Show lisp code for current function.
:v(ariables)    Show local variables, functions, blocks, and tags.
