Which languages have pointer arithmetic, longjmp, goto anywhere within a function, address-of operator, memcpy that is equivalent to assignment even for lexical variables, untagged unions, switch with fall-through in absence of explicit break and a textual/token-wise preprocessor?
Well, there is a big jump between knowing about historic programming languages and familiarity. I know a few things about SNOBOL, but I couldn't sit down and start coding in it without some ramp-up period.
