[julia-users] names(...) sometimes inaccurate?

[Jonathan Malmaud]

I'm been doing some reflective programming and have encountered situations 
where either names(::Module) is inaccurate, or I'm not understanding 
something about module field access. For example,

*julia> **require("DataFrames")*

*julia> **:matrix in names(DataFrames)*

*true*

*julia> **DataFrames.matrix*

*ERROR: matrix not defined*

*julia> *

I've noticed this a few other times. Anyone have insight on what's going on?
