Hi -

I was unable to get in to see Matz' talk at oscon last week, the  
venue was full.
Are the slide available?

I was trying out some of the examples on the slides. Specifically
slide number 57 gave me an unexptected result.

wee% ruby -v -renumerator -e "p [4,2,1].to_enum(:each_with_index).reject{|x,i| i%2==0}"
ruby 1.8.2 (2004-12-25) [powerpc-darwin8.2.0]
[[2, 1]]

Is this 1.9 behaviour?

Thanks,

Emiel

Wait this is supposed to get rid of elements with even indexes; which
it does. Guess the slide is wrong.

It is.  The last minute change was wrong.  Replace "reject" with
"select".
