GE> A programming languaGE from Bell Labs. ALEF boasts few new ideas but is instead a careful synthesis of ideas from other languaGEs. The result is a practical GEneral purpose programming languaGE which was once displacing C as their main implementation languaGE. Both shared variables and messaGE passing are supported through languaGE constructs. A window system, user interface, operating system network code, news reader, mailer and variety of other tools in Plan 9 are now implemented using ALEF. (1997-02-13)
