This is an almost content-free comment. You could have made your comment substantially better by giving some examples of language syntax that makes it easier to write reliable code than unreliable code.

I think that we all agree that Brainfuck and Whitespace are two examples of languages that are very difficult to read. A comment along the lines of "Languages that are difficult to read do not support reliability." is also almost content-free and probably not entirely true. (Some people find C terribly difficult to read -for some reason or other- but very reliable systems have been written in it.[0]) :)

[0] Yes, a quint-squillion unreliable and even dangerous systems have also been written in C. This doesn't invalidate my point.
