Loading modules with using

Now that we've added our folder to the LOAD_PATH, we're ready to use our modules:

julia> using Letters 

At this point, two things have happened:

• All the exported definitions are now directly callable in the REPL, in our case, randstring
• The definitions that were not exported are accessible by dotting into Letters—for example, Letters.rand()

Let's try it:

julia> randstring() # has been exported and is directly accessible 
"TCNXFLUOUU" 
julia> myname() # has not been exported so it's not available in the REPLERROR: UndefVarError: myname not defined 
julia> Letters.myname() # but we can access it under the Letters namespace 
"Letters" julia> Letters.rand() # does not conflict with Base.rand 'L': ASCII/Unicode U+004c ...
