Help with for loop in a macro with varargs

New to Julia

I have the following code:

module Heroku
using HTTP
herokuHost = HTTP.URI("https://api.heroku.com/")
addPath(uri::HTTP.URI, path::AbstractString) = merge(herokuHost, path=joinpath(herokuHost.path, path))
# apps = Heroku.addPath(Heroku.herokuHost, "apps")
macro genuri(p::Symbol)
    return quote
        global $p
        $p = Heroku.addPath(Heroku.herokuHost, $(string(p)))
    end
end
@genuri account
macro genuris(ps::Symbol...)
    return quote
        for p = $ps
            global $p
            $p = Heroku.addPath(Heroku.herokuHost, $(string(p)))
        end
    end
end
@genuris apps news
end
Heroku.account

The macro genuri that deals with a single arg works fine, although I’m not sure whether I should have used $(esc(p)) instead of $p in the assignment.

The varargs macro genuris fails with the error LoadError: UndefVarError: p not defined.

How can I solve this?
