digitalmars.D.learn - Add property setting to chain

```Let i have code:

Clock.currTime.to!DateTime.Interval!DateTime( 24.hours
).fwdRange( h=>h+1.hours ).writeln;

Now if i want to set the minute=0 and second=0 without breaking
chain, what i should do?

with( Clock.currTime.to!DateTime){
minute=0;
second=0
}.Interval!DateTime( 24.hours ).fwdRange( h=>h+1.hours ).writeln;

But it is wrong, because 'with' not return me anything.

```I found this solution:

Clock.currTime.to!DateTime.pipe!( dt=>(dt.minute=0,dt.second=0,
dt) ).Interval!DateTime( 24.hours ).fwdRange( h=>h+1.hours
).writeln;

Or:

Clock.currTime.to!DateTime.pipe!( "a.minute=0, a.second=0, a"
).Interval!DateTime( 24.hours ).fwdRange( h=>h+1.hours ).writeln;

Is this code looks good, idiomatic?

I would probably write a function:

import std.datetime;
import std.stdio;
import std.range;
import std.conv;

DateTime hourPrecision(DateTime dt) {
dt.minute = 0;
dt.second = 0;
return dt;
}

void main() {
Clock.currTime.to!DateTime.hourPrecision.Interval!DateTime(
24.hours ).fwdRange( h=>h+1.hours ).writeln;
}
