Erlang has a weird syntax but again not that far away from being an acquired taste. Python was weird when I started. So was Perl and PHP not so much since. C, C++, Java are all the normal ‘looking’ languages.
These days when I keep coding in Python or PHP, I keep missing the enforced standards of Erlang…
- first class processes
- monitoring oriented programming
- immutable variables
- first class functions
- light weight message passing
- behaviors and OTP
However all of this goes for a toss when I start looking at long term hiring and building a team that can work in Erlang for the long term. And then when I saw Elixir it was neat epiphany. Will there be a time when we will move away from languages and to the Language Virtual Machines.
- JVM has Java, Groovy, Clojure, Scala and many more
- BEAM already has Erlang, LFE and Elixir
Now undoubtedly having immutable values gives a huge power to having a pauseless GC and the BEAM is probably better for it. Had the syntax been more “normal” looking, Erlang has many many ideas that definitely need to be heard and learnt by all. It is sad that Erlang does not have the batteries included approach of other languages (I am looking at you Python), but I think where infrastructure and message architecture is involved Erlang is the best bet for now. Except when a class or a struct is involved it is very rare that we try to reuse a variable for more than one purposes. So with some programmer discipline we can ensure that a variable is never used more than once. In that case can the GC of non-Erlang languages be more efficient?
There are so many ifs and buts but it would be nice to see a solid language succeed.
