So what you're saying is... the language that's holding about 80% of the web together isn't worth taking seriously... because it isn't Erlang? Remind me how many sites are built in Erlang again? Why would lists and tuples be critical in generating html files?

sorry for my English I just mean about these pdf - saw but not see any seriously. I mean that PHP is very seriously but I want some features of Erlang. I love PHP and programming with it but I need pattern matching and long running processes.

Tuples need because they more simple for understand and matching then lists and strings. Tuples can simple converts to lists and back. Tuples more effective with memory.

Only one class can implement tuples now its SplFixedArray. But there bugg when you call createFromArray in own custom class derived from SplFixedArray. Also with small count uts slow.

Try test Erlang and see his power. I hope you think will too, that PHP needs with Erlang features.

Alright, my mistake then.

I'll look at Erlang. I'm trying to wedge self-teaching Python into this semester.

If you need some help for any info about initial Erlang ask me.

For start:

http://www.erlang.org/erldoc

http://rosettacode.org/wiki/Category:Erlang

and you need emacs24+ for good ide and programming with erlang or just use interactive shell erl for initial start.
