Subject: Re: why is else without rescue useless with statement modifiers?

The first definition simply isn't correct. If you want to use the "if" 
modifier, you cannot attach an "else" statement:

<Statement> if <Expression>

Ruby does recognize the "else", but it thinks it belongs to the error 
handling of the method:

def sane?
  sane = true if "a" == "a"
rescue ...
  ...
else  # no exception raised
  sane = "false"
end
