i mean no disrespect. but if something is a piece of crap i will definItely say it's a piece of crap. and yes i am serious when it comes about design.

that kinda puts the fault on the review process. after having seen the buick 2008, i'd have my doubts about buick 2009. yet another also, have you ever given std.getopt a test drive?

put in layman's terms: making it unusable for applications that launch secondary commands was a design goal. and you seem to prefer defending it as it is. you know what. do me a favor. you keep tango arguments. i'll use std.getopt.
