Nimrod looks a lot like someone took Borland's ObjectPascal and removed the begin/end block semantics in favour of whitespace indentation. For example, they use the "var: type" syntax; the syntax for declaring classes is nearly identical; "case [value] of" is right out of Pascal, as is the "0..2" range syntax. They refer to "procedures" as opposed to functions. They even use naming conventions from ObjectPascal: "T" as a prefix for types (eg., TChannel), "P" for the Nimrod equivalent to pointers (eg., PChannel is a "ref TChannel"), "F" for class members. I would not be surprised if the author was an old Turbo Pascal/Delphi hand.
