This is actually calling the function std.conv.text.... this line 
is rewritten to:

std.conv.text(Random(unpredictableSeed).front.to!(string));

The text function converts all is arguments to string and returns 
them all concated together.

It thinks you are trying to use a property setter.

And here, it is calling the text function with no arguments and 
no parens (similarly to a property getter). With no arguments, it 
just returns null.




So this isn't actually a bug, D is working as designed, but it is 
a better example than the common "writeln = 1;" thing given in 
most property setter arguments...
