For completeness, D's 'auto' does not have the same meaning as C++'s
auto. Wait... it actually has! :) But with the meaning of the 'auto'
keyword from the olden C days: automatic storage class. (I correct this
at the end.)
- C has 'auto', meaning "automatic storage class"
- 'auto' is redundant because it's the default anyway
- C++11 re-purposes 'auto' to mean automatic type inference (Ali and
others initially assume 'auto' is the same in D.)
- D has automatic type inference universally without special keyword:
const i = 42; // No auto
- D needs a place holder to satisfy its syntax rules in certain cases
i = 42; // Definition or a typo? Compilation error!
- D brings back the original meaning of 'auto':
// Yes, automatic storage class but now everybody's happy
auto i = 42;
Correction: It's actually the 'auto attribute' in D with the venerable
responsibility of "The auto attribute is used when there are no other
attributes and type inference is desired." Good job, auto! :o)
