I guess the idea of automatic reloading of files after modification has
been reviewed at
https://github.com/JuliaLang/julia/issues/265 and
https://groups.google.com/forum/?fromgroups=#!topic/julia-users/38pKvFP0ynM
So instead of asking if it's possible to skip the 'include', I'll just add
my support for making this change.
