Description
Summary:

Since Lisp is a #1=(programming . #1#) language, lisp code is executed at compilation-time.

Given the restrictions on mocl repl, it would be important to provide better debugging information upon compilation-time errors.


Steps to Reproduce:

Compile some file with a compilation-time error.

Expected Results:

An error report with at least a full stack dump.

Actual Results:

An insufficient "Control stack exhausted".

    This is probably due to heavily nested or infinitely recursive function
    calls, or a tail call that SBCL cannot or has not optimized away.

    PROCEED WITH CAUTION.
