digitalmars.D.learn - Can't instantiate SimpleTimeZone

reply Andrej Mitrovic <andrej.mitrovich gmail.com> writes:
I was using the AE[1] library, but recently it started to fail to
compile due to essentially this:

--------
import std.datetime;

void main()
{
    Duration dur;
    auto x = new SimpleTimeZone(dur);
}
--------


 test.d(8): Error: immutable method std.datetime.SimpleTimeZone.this is not
callable using a mutable object
 test.d(8): Error: no constructor for SimpleTimeZone


The only constructors available for that class are all immutable.

Why the breaking change? Did it break on purpose? And why is the error
message so awful?

Thanks, that does explain it. I have to put this in the changelog ASAP.

Chances are the 2.063 release is going to be one of the most breaking
releases ever.
