redirecting in jester from outside the routes block

[random898989]

Can someone please help me understand why calling baz() doesn't really seem to 
redirect in "/bar" (and falls through ending up responding "uh oh")? I thought 
templates expanded verbatim inline?
    
    
    import jester, asyncdispatch, htmlgen
    
    template baz() =
        redirect "/foo"
    
    routes:
        get "/foo":
            resp h1("in foo")
        get "/bar":
            #redirect "/foo"
            baz()
            resp h1("uh oh!")
    
    runForever()
