Not sure if this means snail mail, but I don't know why I never considered that before email, people used physical mail for things like tech support, heck, maybe submitting patches
We also covered Scheme, Prolog, and . . . Java. :-) Okay this was the 90s when OO was new, but still maybe they should have gone with something like Smalltalk.
I once was paid real money to develop in VA Smalltalk. It was a fun language. Dave Ungar and Dan Ingalls said a few things that made me think they planned at one point to add spitbol-esque features to Smalltalk. And Alan Kay once quipped something about wishing he had seen scheme before writing smalltalk grammar.
For better or worse, bits of Smalltalk live on in Java and Ruby and bits of Scheme can be found in JavaScript if you look hard enough. Where did Icon and Spit/Sno-bol wind up? Alas.
And .NET/C#, as Java nemesis :)
