Do you know if the following four problems are already present in Bugzilla? I don't remember (the only problem I am more sure is not present in Bugzilla is the missed priting in the first program).
---------------------------- import std.algorithm, std.stdio; void main() { int[int] hash = [1:2, 3:4]; auto vals = hash.byValue(); writeln(vals); // int delegate(int delegate(ref int)) map!q{a}(vals); } The writeln doesn't print the items. And the last line causes this: ...\dmd\src\phobos\std\algorithm.d(110): Error: template instance Map!(result,int delegate(int delegate(ref int) dg)) does not match template declaration Map(alias fun,Range) if (isInputRange!(Unqual!(Range))) ---------------------------- void main() { auto a = [,,,,,,,,]; } This is ugly. ---------------------------- struct Foo { int x; this(int xx) { this.x = xx; } } void main() { enum f = Foo(10); } DMD 2.052 refuses this code that looks valid. --------------------------- Thank you, bye, bearophile
