The presentation of evaluation is confusing. He also claims that it has simple syntax and semantics, which is not true at all. Most real Lisps have complex syntax due to special operators, macros and various extensions to s-expressions. Also semantics of the special operators and the macros is far from trivial. The first comment claims that because there is syntax for vextors, the language is not homoiconic (a term I don't like at all), which is also not true. Confusion all around. Generally it is true though, that the code is data / data can be code feature of Lisp makes understanding source code more difficult. A language without that feature is easier to understand. Then there is the issue of syntax based on prefix expressions. Whether this is easier or not depends and is not that clear. Is code with fully parenthized prefix expressions actually easier to understand than a syntax with mixed (prefix, infix, postfix) expressions and a complex operator hierarchy?
