http://d.puremagic.com/issues/show_bug.cgi?id=4607 Summary: Make .byValue() and .byKey() of associative arrays adopt the input range interface. Product: D Version: D2 Platform: Other OS/Version: All Status: NEW Severity: enhancement Priority: P2 Component: druntime AssignedTo: sean@invisibleduck.org ReportedBy: kennytm@gmail.com --- Comment #0 from kennytm@gmail.com 2010-08-09 10:26:46 PDT --- Currently .byValue() and .byKey() returns a delegate. This make it only iterable by foreach, but cannot be used in std.algorithm algorithms, e.g. ---- import std.algorithm; import std.stdio; void main () { auto x = ["a":4, "b":6]; writeln( reduce!"a+b"( map!"a*a"( x.byValue() ) ) ); } ---- While it is possible to use .values and .keys, both of these create a copy of the array, which is unnecessary for many codes like the one above. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- |
