Alef (programming language)
From Wikipedia, the free encyclopedia
The Alef programming language was designed by Phil Winterbottom of Bell Labs as part of the Plan 9 operating system.
In a February 2000 slideshow, Rob Pike noted: "…although Alef was a fruitful language, it proved too difficult to maintain a variant language across multiple architectures, so we took what we learned from it and built the thread library for C."

[edit] Example
This example was taken from [1]. The piece illustrates the use of tuple data type.
(int, byte*, byte)
func()
{
return (10, "hello", ’c’);
}
void
main()
{
int a;
byte* str;
byte c;
(a, str, c) = func();
}

[edit] Trivia
