Re: std.parallelism taskPool.map example throws exception

[Jay Norwood via Digitalmars-d-learn]

This appears to work ... at least, no exception:

        auto sm = File(fn).byLine(KeepTerminator.no)
                .map!"a.chomp"()
                .map!"a.idup"()
                .map!(to!double)
            .map!"a.log10"()
                .sum();

        writeln("sum=",sm);
