Maybe something like this should work:
julia> macro A()
esc(quote
a=5
b=7
end)
end
julia> function f(x)
@A
x+a+b
end
f (generic function with 1 method)
julia> f(5)
17
If you don't want your variable names to be mangled then do the `esc`.
So, basically just write normal code in the `esc(quote ... end)` bit.
