 # Quote of the Week
 
-> I said it before, and I'll say it again: If one views Rust as a critique on C++, one should view it as a constructive critique.
+> > Heard recently creative coding experience which rust gives. What about unconscious coding experience - do whatever you can to make your code compile as late as you can, then go sleep and find your code correct and working in the morning
+>
+> Woah, I know people say the Rust compiler is slow but I never had a Rust program that took all night to compile☺
