2. type the following

ex.args[1].args[2].

Seems like a bug in Base:

julia> ex = :(function foo(::Int) end)
:(function foo(::Int)
      #= REPL[6]:1 =#
  end)

julia> ex.args[1].args[2].┌ Error: Error in the keymap
│   exception =
│    BoundsError: attempt to access 2-element Array{Any,1} at index [3]
│    Stacktrace:
│     [1] getindex at ./array.jl:731 [inlined]
...

A similar error, thrown from the same function in REPLCompletions.jl, two lines earlier:
After using Plots, typing

plot(log.(x),

produces

BoundsError: attempt to access 1-element Array{Any,1} at index [2]
getindex at array.jl:731 [inlined]
get_value_getfield(::Expr, ::Function) at REPLCompletions.jl:355
get_value_getfield(::Expr, ::Module) at REPLCompletions.jl:357
[...]

Edit: seems this was reported in #209 without reproducing code.
Edit 2:
can be reproduced without Plots, with

log(log.(x),

or any other currently defined variable in place of log (x doesn't have to be defined to trigger the error).

Fixed with JunoLab/Atom.jl@4af4d3e on our end.
