Some of the dmd error messages need some tweaking.
import std.datetime;
auto t = Clock.currStdTime;
writeln(to!string(t));
Result in:
Error: template core.time.to cannot deduce function from
argument types !(string)(long), candidates are:
C:\D\dmd2\windows\bin\..\..\src\druntime\import\core\time.d(1709): core.time.to(string units, T, D)(D td) if (is(_Unqual!D ==
TickDuration) && (units == "seconds" || units == "msecs" || units == "usecs" || units ==
"hnsecs" || units == "nsecs"))
import std.datetime;
import std.conv;
auto t = Clock.currStdTime;
writeln(to!string(t));
Solves the issue but its strange that there is no error message
indicating that to! needs the std.conv included. Technically one
can argue that the original message mean that but its very, very
unclear.
