function(test)

endfunction(test)
test()

function(test)
  message("2")
  _test()

function(test)

Michael's suggestion would help too, though it might be called a hack.
 The expressiveness of the language could be improved if we could
allow symbols in the function namespace to be copied or renamed:

  set(&test3 &test)  # bind function symbol "test3" to value of
function symbol "test"
  function(test)
    message("3")
    test3()
  endfunction(test)
