     It is yet more complicated than that.
     For example, Verilog-XL does not "inline" every macromodule, only macromodules
     which obey certain restrictions.
     
     Frankly, since any implementation-dependent change destroys the portability of
     the code, I would like better a statement whose spirit is that by default a
     macromodule is the same as a module, but an implementation may add a special
     mode which may be switched on or off which treats macromodules differently.
