Comment On Fonction à 2000€

Je me suis souvent demandé quel type de ligne de code on obtenait quand on payait un consultant à 205€ de l'heure. Je pensais que ce ne serait pas un code incroyable . Mais maintenant que j'ai effectivement vu (merci Will Nesbitt) le code produit par un consultant à 2000€ d'IBM, je peux dire que c'est effectivement grandiose... mais pas dans le sens que je l'espérais.
