# Five lines of code that will make your underscore + CoffeeScript use cleaner.
# Creates an underscore function for each function in to_reverse with R (short for Reversed) appended to the name.
# The R version moves the function argument (first argument in normal underscore) to the end, 
# so you can write:
$(window).scroll _.throttleR 500, ->
    console.log "This print's at most every 500ms"

# Instead of:
$(window).scroll _.throttle ->
        console.log "This prints at most every 500ms too"

• Getting projects that rely on a particular version of X, Y or Z external software being installed to even boot up
• Gems that rely on n number of other gems that are locked to a particular version - how many of us have had to fork an open source lib just to mess with the locked versions
• Gems that rely on C extensions that are built against specific system installed libs
• Running bundle update always seems to take way longer(1) on a non trivial project than in other ecosystems dependency management systems such as Clojure/Leningen or Node/npm etc

I'm not saying things are perfect in other languages. Heck, although I can just about use SBT I refuse use Scala because it seriously grates me in so many ways. And Go, which I love as a language has only recently started seeing some decent attempts with projects trying to deal with the difficult problem of dependency management.

I know some of my points above can be rectified by engineers just using a bit of common sense in their projects. I love writing apps
