Yes, and that's the syntax Tilman was pointing out. That is valid
Ruby. Nikolai misunderstood, suggesting it be rewritten as what you
see above. The two code fragments are, however, not equivalent.
Tilman's code is valid and does not indent correctly.
Nikolai's code is invalid, but indents correctly :)
P.S. I repeat: the following two fragments are _not_ equivalent!
puts(x) rescue nil
If the second fragment were legal, they'd be equivalent (I guess) but
only for the special case where there's only one line in the block!
