Interesting rant about Scala's issues

[Bienlein]

My knowledge of compiler constructions is fairly limited and I 
might be wrong, but it seems to me that the Scala compiler is 
broken. Scala has gained some bad reputation for long build times 
(just google for Scala and build time) which IMHO cannot be 
explained by the large number of language features. D has a 
comparable large number of language features and compiles much 
faster than Scala.

D has been designed from the beginning with caution on 
compilation speed and thinking about how to keep it slow to begin 
with. D not only in that way is a language that was thought out. 
On the contrary, Scala seems to me to be a language where many 
features of various languages were thrown into one and then a 
compiler was built for it. The incremental Scala compiler pretty 
much rescues the build time problem, though, and they are mostly 
lucky now. Also, IMHO, implicits are really crazy and it should 
have been clear from the beginning that they will become a 
problem for scalable build times, see 
http://java.dzone.com/articles/implicits-scala-conversion. 
Interestingly. Martin Odersky got his Ph.D. from Niklaus Wirth at 
the ETH and I don't want to know what Wirth would say about 
implicits.

The presentation by Paul Phillips was discussed in the Scala 
forums at great length:

Sadly, the only serious language on the JVM besides Java8 is 
Scala. Ceylon has not taken off at all after becoming 1.0. 
Groovy's language extensions are basically AST transformations 
and not truly baked into a "real" language. Nobody knows how 
Kotlin will be doing when it turns 1.0 maybe somewhen in 
autumn/winter this year.

To get a plus for your skill set when applying for Java jobs you 
will have to learn Scala. For a Java developer like me any 
chances for a job doing D are very slim. But I keep looking into 
D just out of interest and to get some food for my mind. There is 
so much to learn from looking at D and playing with it that I 
keep doing it just on a fun & interest basis.
