If you want to debug Julia itself, you can use gdb/lldb on it. That plus using the `jl_` function to dump values gets you a pretty decent debugger if you're comfortable in gdb/lldb, but it's not an experience that most Julia users would be happy with and you cannot evaluate code in the current stack frame's context or set breakpoints with Julia expressions as conditions. Debugger.jl lets you do all of that.
