|There are no post- or pre-increment or decrement operators!
No. Because I couldn't give them object-oriented semantics. They
would be essentially assignments.
|There's nil? but no notNil? Why? I realize that there's unless and until...
|(yes, I know I can make my own).
No paticular reason, except A) I don't like Smalltalk-ish naming
convention, e.g. "nonNil?" B) we already have not/unless/until, so "if
a.notNil?" is fundamentally same as "unless a.nil?"; I felt we don't
need this one.

use rubydb.el, if you're Emacs user. It works just like gdb-mode for
Emacs.
|How do I get vi mappings in the debugger? It tells me that emacs mode is
|available... I got vi mappings going in irb.
"emacs mode" here means that you can run it under Emacs using
rubydb.el. But since the debugger uses readline, which provides vi
binding, I think you can get vi binding (I've never tried). Check out
GNU readline document. I think you have to configure your ~/.inputrc
file.

"ri" can serve for you. It's online version of the reference section
in the pickaxe book. Fetch it from

Not yet.

Maybe. But I'm Japanese. Ruby is not English. It's the basic naming
rule to avoid third person singular form in the standard libraries.

|a.respond_to?('||=') returns false. Why doesn't it complain?
Because it's not a method. Abbreviated assignment (argumented
assignment) is combination of operator and assignment. In addition,
"||" is not a method neither. See page 220 of pickaxe book.
|Surprise! 0 isn't false, but the ||= operator doesn't complain about the

Because it's true. Everything but false nor nil is true.
|p = Proc.new { |a| a }

|I would have either expected a warning or the second parameter to be ignored.
Ah, it will be solved in the future. For now, you have to use
p = Proc.new{|a,| a} # notice "," after "a"
to specify single parameter to the block. {|a|..} works like
{|*a|..}, if multiple arguments are passed to the block.
|If you call a method with the wrong number of arguments, you get an error
|message. But not a Proc.
Proc does check number of arguments, e.g.
p = Proc.new{|a,b| p [a,b]}
p.call(1) # error!
But as I explained before, you have to specify "a," for single
parameter to enable argument number check.
