More generally, I've never understood why some people insist that certain features make Ruby better for DSLs -- are code blocks really that important to DSLs? Or is it just the lack of parens??
Comparison to JavaScript suggests that it's the blocks that make the difference. Even the fact that you have to spell your blocks with "function(){...}" doesn't stop you from making a usable DSL, it's just not always as pretty as you'd like.
The lack of parens and simpler syntax for blocks in Ruby just makes it easier to make *nice-looking* DSLs.
