I'm using rails for my company but ruby is definitely not my preferred language. Blocks/Procs/Lambdas (why are there three almost identical constructs?) definitely don't compare to function application / currying. I'd much rather write in F# but I'm worried about all the nice to haves that come with the rails stack, like capistrano or the plugins to serve/upload your assets to S3. (e.g. ASP.NET has HAML but not sass)…
I fixed that this past weekend :)
