I cannot reproduce. Do you have anything in your startup or are you using a custom system image?

[vlad-circadia]

Good point: the issue indeed is not present when julia is started without startup file:

➜  ~ julia --startup-file=no
               _

julia> bar = Dict(:a=>1)
Dict{Symbol, Int64} with 1 entry:
  :a => 1

julia> bar[:a]
1

In the startup file I've got:

➜  ~ cat .julia/config/startup.jl
using OhMyREPL
using Revise

OhMyREPL seems to be the culprit.

I'm quite surprised how OhMyREPL.jl can break dictionaries in general like that...

Yeah, me too. I'd be curious to find out what's causing it though. May be it is something else that goes wrong with my setup...
