If I could clean up the little quacks that Ruby gives here and there.

Object.inspect

Currently:

 => #
 => #
 => #

Slight polish:

 => (Object)
 => (Book @title="Gorbachev's Finger Tricks",
    @author="Gorbachev", @length=150)
 => (File ruby.h)

Proc.inspect

Currently:

 => #

Show arity?

 => (Proc |a,*b|)

Backtraces and Warnings

Currently:

 bin/tiny_wm.rb:4: parse error, unexpected '='
 $d = = X11::Display.new
       ^

 bin/tiny_wm.rb:2:in `require': no such file to load -- X11/Display (LoadError)
        from bin/tiny_wm.rb:2

 ArgumentError: wrong number of arguments (3 for 1)
        from (irb):1:in `gets'
        from (irb):1

 /home/why/bin/warn.rb:2: warning: parenthesize argument(s) for future version

Slight polish:

 ParseError in bin/tiny_wm.rb (line 4): 
   unexpected '='
   > $d = = X11::Display.new
   >       ^

 LoadError in bin/tiny_wm.rb (line 2) at `require':
   no such file to load -- X11/Display
        from bin/tiny_wm.rb (line 2)

 ArgumentError in irb (line 1) at `gets': 
   wrong number of arguments (3 for 1)
        from irb (line 1)

 Warning in /home/why/bin/warn.rb (line 2):
   parenthesize argument(s) for future version

We should avoid wrapping the `message’ inside the initial line of a backtrace. It is often the most crucial part.

It sure would be nice to have the ability to customize the look of your backtraces. To have backtrace objects like in Sydney. I’d like to brightly ANSI highlight the backtrace line which refers to $PROGRAM_NAME, give a dark color to trace lines from the stdlib and medium highlight everything else.

I’m sure all of you out there can give help here. But you know what I mean about some of these?
