  When compiling  .zcompdump to .zcompdump.zwc I think it will start a
  little faster...but when will .zcompdump be created...and -- as a
  logical consequence -- when do I have to recompile it again ?

  Is there any automatism? Kinda "Dear ZSH, if you have recently
  created .zcompdump...please compile it for me..."

  (or am I blinded by too much programming tasks ???)

  Less features means being fast...isn't it ?
