Euclid

language (Named after the Greek geometer, fl ca 300 BC.) A

Pascal descendant for development of verifiable system

software. No goto, no side effects, no global

assignments, no functional arguments, no nested procedures, no

floats, no enumeration types. Pointers are treated as

indices of special arrays called collections. To prevent

aliasing, Euclid forbids any overlap in the list of actual

parameters of a procedure. Each procedure gives an imports

list, and the compiler determines the identifiers that are

implicitly imported. Iterators.

Ottawa Euclid is a variant.
