To require ref at the callside was proposed long ago. Dunno if
this would
make Manu's task harder. I agree, that this might have been
better in
the long run.
another "cosmetic issue" that bugs me alot.
p.s. and with pointers it's easy to write something like this:
auto parseNumber (string s, bool* error=null);
yes, i know about exceptions... which blocks `@nogc`. not yummy.
You could preallocate the exception or use an out parameter.
