Is it possible to specify in `map` to return the result
`[a.key] = a.value`? To make the result look like `[key:[val],
key:[val]]`
Wow. This is an old thread....
.. anyway... how about making custom strings out of the KV pairs:
void main()
{
import std.conv : to;
import std.algorithm : sort;
import std.stdio : writeln;
auto foo = ["VXE":8, "BZP":5, "JLC":2];
string[] orderedKeyPairSet;
foreach (ref kv; foo.byKeyValue)
{
orderedKeyPairSet ~= kv.key.to!string ~ ":" ~
kv.value.to!string;
}
orderedKeyPairSet.sort;
foreach(ref str; orderedKeyPairSet)
writeln(str);
}
/*
output:
BZP:5
JLC:2
VXE:8
*/
