Subject: Re: What are your ruby rough cuts ?

Here are a few things I can think of:

* Regexp ^ and $ work match more than just start and end of string. For 
example, /^abc$/ does not match only "abc" but also "rm -rf /*\nabc"

* http://innig.net/software/ruby/closures-in-ruby.rb

* Using write accessors: you must write self.foo=123 instead of foo=123 
(the latter sets a local variable)

* Similarly, having to use self.class instead of class

* auto-splat

* class variables (@@foo), just try working out the semantics

* Lots of junk inherited from Perl, such as implicit operations on $_ 
and flip-flop operator

* Spaces are semantically important, even within a line

  puts (-3).abs     # prints 3
  puts(-3).abs      # raises NoMethodError

* The whole of ruby 1.9 String handling is arguably one huge paper cut.
