Change Log: 2.041

New/Changed Features

• __traits allMembers and and derivedMembers now return a tuple of strings rather than an array of strings. Enclose __traits in [ ] to make array literal. This makes it possible for foreach statements to iterate at compile time over it.
• Interface member functions can now have contracts.
• Added new operator overloading regime.
• Warnings no longer halt the parsing/semantic passes, though they still return an error status and still do not generate output files. They also no longer count as errors when testing with "compiles" traits.
• Added -wi switch for Bugzilla 2567
• Mixin template definitions should be preceded with mixin
• Add !in operator.
• Associative array contents can now be compared for equality
• Use of length inside of [ ] is now deprecated, use $ instead
• Added toDelegate() to std.functional to convert function pointers to delegates.
• Implemented attributes for constructors.
• Implemented qualifiers for struct literals, like immutable(S)(1,2,3)
• Array equality can now be done with differing array element types.
• Add simple spell checking.
• Bugzilla 3378: [tdpl] ++x should be an lvalue
• string, wstring are now bidirectional (not random) ranges
• std.algorithm: defined move with one argument; levenshtein distance generalized to with all forward ranges; take now has swapped arguments
• std.array: empty for arrays is now a @property; front and back for a string and wstring automatically decodes the first/last character; popFront, popBack for string and wstring obey the UTF stride
• std.conv: changed the default array formatting from "[a, b, c]" to "a b c"
• std.range: swapped order of arguments in take
• std.stdio: added readln template
• std.variant: now works with statically-sized arrays and const data
• std.traits: added isNarrowString
• The default type for [1,2,3] is now int[] rather than int[3].
