GHC can be freakishly slow, especially with -O which is needed and is on the whole a lot slower than scalac, yes. You can claim otherwise of course, but oh look, it even has bugs in it:
https://stackoverflow.com/questions/17822539/debugging-compi...I never dismissed Paul Philips' arguments. In case you missed my not-so-subtle critique, I'm complaining about people referring to his presentation as a tool for bashing Scala, without having listened to those arguments. What's a "mess" anyway? Scala-js.org happened in a fantastic time-frame because it reuses Scala's reference compiler. How many languages can claim such performance?
People are also working on fixing many of the problems raised by Paul Philips, with Scala 2.11 being a result of that work. And oh look, Paul Philips is still on the contributors list, amongst many others: http://scala-lang.org/news/2014/03/20/release-notes-2.11.0-R...
You're doing both an appeal to authority for an otherwise unconstructive criticism (yours, not Paul's) and an ad-hominen in absence of actual arguments. Also for a random fanboy, at least I'm putting a real name behind my 2016 days old account ;-)
