What about "fn" or "fun", for "function"?

how about an uppercase lambda (instead of the usual lowercase one)

Even though I see the usefulness, that's just ugly.

That is, Matz introduced the -> syntax in mid-2005. There were two years 
and five months for discussion of the feature.  And then 1.9.0 was 
released at the end of 2007.  It seems to me that that should be the end.

Matz is Ruby's benevolent dictator. He's a smart guy and he's put a lot 
of thought into this. If you like the language he created, you've got to 
trust his ideas about good syntax. (As an aside, I wonder whether the 
Japanese developers on the ruby-dev mailing list give Matz as much grief 
as we seem to here :-)

My understanding is that 1.9.0 is headed, relatively quickly, toward a 
stable 1.9.1 release.  If we really don't think that -> is the optimum 
lambda syntax, it seems to me that we should wait until the 2.0 
development tree opens.
