 -optimize, optimization on generated code.
        The default is share for concrete, none for resource modules.
+       Each of the flags can have the suffix _subs, which performs

     -optimize=share        share common branches in tables
     -optimize=parametrize  first try parametrize then do share with the rest
     -optimize=values       represent tables as courses-of-values
