View source for Differences With TDPL

The following is a list of differences between D2 and The D Programming Language book by Andrei Alexandrescu.

These need to be verified. This list was simply gathered from a [http://forum.dlang.org/post/mailman.647.1327135415.16222.digitalmars-d-learn@puremagic.com| post by Jonathan M. Davis] on the NG to get this page started.

== New Features ==

=== Weak vs Strong Purity ===
http://klickverbot.at/blog/2012/05/purity-in-d/

=== New Lambda Syntax ===
http://dlang.org/expression.html#Lambda

=== New Alias Syntax, Alias Templates ===
http://dlang.org/declaration.html#AliasDeclaration

=== Attribute Inference for Templates and Function Literals ===
http://dlang.org/function.html#function-attribute-inference

=== IFTI now uses the tail-const type of arrays and pointers ===

== Unimplemented Features ==

=== Multiple alias this ===

You can only have one subtyping member currently.

=== Shared ===

Not all of shared's guarantees are implemented yet.

=== SafeD ===

@safe (and therefore SafeD) isn't fully implemented. So, it doesn't 
necessarily work quite like it's supposed to yet.

== Differences ==

=== Overriding private methods ===

According to TDPL, you can override private, but right now only public and 
protected functions are virtual. I'm not sure that it's 100% clear whether the 
compiler will be changed to match or whether TDPL is going to have to be 
changed. You can look at http://d.puremagic.com/issues/show_bug.cgi?id=4542 
for details.
