[julia-users] Re: How should I structure my code?

````

macro need_m()
    :(m * 20)
end

function algoX()
    m = 10
    @need_m
end

algoX()

# 200

````

I think you can create two similar macro to solve your problem.
But i think this is bad practice.

I think you should create some code without a scope, as I know, the macro 
can do such thing.
