This also works, though it isn't shorter. It looks nice, though.

You could save that line into a separate file as a library, and then actually call it really easily!

@Sakari, I don't this is "stupid," if you're trying to learn Ruby (like me).
Anyway, I think that do end is the same as {}, so could be written (shorter)...
[I'm sure my code will be totally weird here]...

@Daniel Rosenstark yes do / end and {} are both closure literals when in the correct context. {} us typically used for one-liners where as do / end in multi-liners (not always the case though obviously) this is a pretty funny exercise, the range splat is cool though. I am not sure exactly of the C implementation but splat does call #to_ary so you can do things like this

I'm learning Ruby/Haml and this is useful to learn.
I'm actually looking for a way to do the same thing taking the number from a symbol variable. Something like the code below, but any version doesn't work.
How could I better make it work?
