IMO impure functional languages like Common Lisp, ML, Scheme, and the
somewhat ironically named Pure language are straightforward extensions of
imperative programming: you can make your code less imperative without
being completely deprived of it.  All of these are tail-recursive (formally
CL is not, but most implementations are) which means that recursive loops
become non-recursive gotos, and for/do-loops wind up being pure without you
noticing.

leader of the House of Commons, he may well begin to comprehend how the
Egyptians worshiped an insect.  --Benjamin Disraeli
