 The whole macros issue comes to a tradeoff between
 power+expressiviness X readability. 

 IMVHO, macros are readability assassins. The power (for any developer)
 to introduce new syntax is *not* a desirable feature, but something
 to be avoided. And that alone should be a stronger argument than
 a hundred use cases.
