Subject: Re: Sort and a multiline block

From: Phrogz [mailto:phrogz@mac.com] 
# This line:
# p foo { ... }
# is interpreted as
# p( foo{ ... } )
# 
# While this line:
# p foo do ... end
# is interpreted as
# p(foo) do ... end
# 
# The lower precedence of do/end is causing it to be bound to the result
# of p( foo ), or in your case p( array.sort )

indeed, but the sad part really is ruby does not check blocks, like as if they float silently like shadows :( 

eg

> p{|x| p x}
=> nil

> puts{|x| p x}

=> nil

> "sdf".upcase{|x| p x}
=> "SDF"

> def m
> end
=> nil

> m{|x| p x}
=> nil

i would consider those as bugs though :(

i just wish blocks were like clear and visible proc params.
