cannot import horner macro

[simonbyrne]

I want to use the horner macro in a package, however when I try to import it, I get the following error:

julia> quantile(Normal(),0.1)
ERROR: r not defined
 in Φinv at /Users/simon/.julia/Distributions/src/univariate/normal.jl:60
 in quantile at /Users/simon/.julia/Distributions/src/univariate/normal.jl:141

But it works fine if when redefined in the package.

Fortunately this is pretty straightforward --- the horner macro was originally designed to be used only in the module where it is defined, so it does not use esc where it should. I guess this is a risk of using a non-exported macro.
