Metaprograming, function eval not works as expected

New to Julia

I has had always been confusing on Julia Metaprograming. Here is an example:

I have a variable:

const SAer = 1

How can I define a macro like:

macro Ticker_str(x)
    #do someting
end

to get this:


v=Ticker"SA"
# v === SAer
2 
julia> const SAer = 1
1

julia> macro Ticker_str(x)
           return esc(Symbol(x, "er"))
       end
@Ticker_str (macro with 1 method)

julia> v = Ticker"SA"
