Ruby Issues:

  • named parameters (is this in 1.8?), these are really
    handy for GUI objects
    with many valid options that are partially set by the user.

Easy enough to do as is with a block, provided the package author simply
provides a “yield self if block_given?”.

e.g.

class Foo_Widget
attr_accessor :height, :border, :bgcolor
def initialize
yield self if block_given?
end
end

o = Foo_Widget.new{ |f|
f.height = 10
f.border = 2
f.bgcolor = “red”
}

p o → #<Foo_Widget:0x28ac140 @height=10, @bgcolor=“red”, @border=2>
