[MacRuby-devel] looking for ruby-sher syntax

Code works for me, so it's not really clear to me which #transform
method you are missing. Regarding the style, I prefer to use
parenthesis, which makes it a bit clearer. If you really dislike it
and have to use it many times, you could of course wrap it:

$ macirb
irb(main):001:0> class NSAffineTransform
irb(main):002:1>   def translate(x, y)
irb(main):003:2>     translateXBy(x, yBy:y)
irb(main):004:1>   end
irb(main):005:0> end
=> nil
irb(main):006:0> transform = NSAffineTransform.transform
=> #<NSAffineTransform:0x20022c040>
irb(main):007:0> transform.translate(20, 20)
=> #<NSAffineTransform:0x20022c040>

Laurent: Coincidentally, I tried to alias translateXBy:yBy: to
translate, but when calling it it gives this error:

irb(main):013:0> transform.translate(20, 20)
ArgumentError: wrong number of arguments (2 for 2)
