Precompilation problem with tuples

[cstjean]

I have a weird problem with precompilation, and the latest unit changes. If I have a package called BlagData, containing

module BlagData

using Unitful

wab = [("a", Unitful.l),
       ("b", Unitful.°C),]

end

and I run the following code, I get an error: (using Julia 1.0.1 Linux, on Unitful#master)

julia> using BlagData, Unitful

It only happens with celsius or fahrenheit.

EDIT: shortened example

That is weird. I don't have an immediate answer but I'm looking into it.

I don't think there's anything to be done here.
