Code snippet:
import core.time: TickDuration;
import std.datetime: StopWatch, AutoStart;
void main()
{
auto wait = TickDuration.from!`msecs`(1000);
auto timer = StopWatch(AutoStart.yes);
while (timer.peek < wait) // Okay.
{ }
while (wait >= timer.peek) // Compile error.
{ }
}
Compiler output:
comparison.d(13): Error: function core.time.TickDuration.opCmp (ref
const(TickDuration) rhs) const is not callable using argument types
(TickDuration)
comparison.d(13): Error: timer.peek() is not an lvalue
I assume the same thing happens elsewhere in the library. As D strives to be an
intuitive language, I reason this to be a bug. "<" and ">=" should work
identically in this circumstance.
