REPL functions crash the debugger

KristofferC commented 5 years ago

julia> function f(x)
           return x
       end
f (generic function with 1 method)

julia> set_breakpoint!(f)
2-element Array{MagneticReadHead.Rule,1}:
 MagneticReadHead.Rule{typeof(f)}(f, 0)

julia> @iron_debug f(2)

Maybe make the file for REPL input the history file instead?

That, or perhaps use CodeTracking.jl's definition function.

I'll need to work out how REPL methods calculate there lineinfo.

Steal this: https://github.com/JuliaDebug/Debugger.jl/blob/master/src/locationinfo.jl#L23-L28
