[julia-users] Re: Why is Forward Reference possible?

[Matt Bauman]

This is very intentional and is addressed in the manual 
(http://docs.julialang.org/en/release-0.3/manual/variables-and-scoping/?highlight=forward).
 The key thing to realize is that functions are just global identifiers, too. 
If forward references weren't possible, Julia would require c-style forward 
definitions and header files.
