Hmm, can't resist commenting on this one!

Some cherry-picked quotes from the manifesto:

- Visual languages are not the solution: ... common idea is to replace AST
structures with some form of graphical diagram. ...
Agree, point and grunt is much slower than entering commands. Its like
being stuck in a country where you don't speak the language - all you
can do is point at things and grunt ('click') and hope they understand you.
- Programming is not Mathematics
Disagree strongly... Bad programming seems to have little to do with
mathematics, good programming often has the elegance of a well thought
out proof. Beauty in programming is like beauty in mathematics.
- Change is natural: There has been much effort expended to remove the
concept of mutable state from programming, to be replaced by immutable
values as in mathematics. This is entirely misguided. ... Monads are a
reductio ad absurdum. [ Heresy! :-) ]
Change is natural, but that has nothing to do with mutable state.
Parallelism will make mutable state less attractive, as will
hardware/software co-design. Isolating changes within a verifiable
sandbox (like the ST/State monads) reduces errors due to unforseen
interactions.
- Control flow considered harmful: ... The primary reason for this is to
permit side-effects to be ordered by the programmer. ... [ This appears to
contradict the criticism of monads. ]
Agree - control flow causes the possible paths (or corner cases) in the
program to increase exponentially. Program correctness verification becomes
much harder with more possible-paths.
