Re: [julia-users] Overriding when the function is used elsewhere

[Magnus Lie Hetland]

Just a quick followup: What if identifier wasn't defined in a.jl – what do 
I do then? That is, I'd like an abstract, un-implemented "template method," 
sort of. There'd be no way to import it into b.jl, and therefore no way to 
"inject" its definition into a namespace available to identify. Should I 
explicitly implement a function that raises a "no method" error, or 
something? (Or am I once again missing some basic language construct?-)
