1.0 adoption path?

The same features that make Julia so much faster than interpreted languages like Matlab and Python also make it much harder to implement tools like debuggers. This isn’t for lack of effort – it’s inherently harder to debug a fully JIT language implementation like Julia’s than it is to write a debugger for an interpreted language runtime.

I am going to say something delibrately provocative here. I often see responses here along the lines of “I would love to use Julia but there is no IDE and no debugger”
Regarding an IDE the Atom/Juno combination looks pretty good to me. There are extensions for VisualStudio.

But for a debugger - how much of a barrier is that in reality?
Did Grace Murray Hopper have a debugger - apart from a flyswat and sellotape?
