milktrader/Quandl.jl#43

[merl-dev]

I have been having the same issue, and hasn't affected my code. It is annoying though when I have to demo work and I have to say "Don't worry, it's not a problem". Definitely making my Julia pitch more difficult. (shows up when using the AWS package, from which the dependency arises)

[WestleyArgentum]

This annoys me too - I've filed issues in Calendar and DataArrays, which cause the ambiguity. I think we should probably focus discussion in DataArrays: JuliaStats/DataArrays.jl#115

[quinnj]

Closed by #11.
