Thanks Moritz,
it just felt like I should be able to leave out the "+ 0i" since that's
how I wrote them when studying maths;)
Thanks for the shiny new toy;)
Regards,
Michael

This conforms to the current specification. If you want something that
accepts both Complex and Real numbers, use 'Numeric' as type constraint.
Please notice that numeric type hierarchy in Perl 6 is not based on
subset types (as the mathematical hierarchy is), mostly for performance
reasons.
Note that in order not to surprise the casual programmar, (-1).sqrt
fails, while (-1 + 0i).sqrt returns one of the complex square roots.
The idea is that if you know about Complex numbers, you know what you're
doing.
Cheers,
Moritz
