I think the idea is that if your programming language keywords are all
English anyway, you might as well have them make sense *as* English.
That makes it easier for English-speakers to learn, without making it
harder for non-English speakers - except for the fact that it's
different from other

I found some of the perl 6 new features really neat:
- creating your own type
- type casting
- junctions
- multidispatch
- :r:w:a shortcuts
- hyper operators
