>Clojure is a language for people who know what they are doing by people who know what they are doing.

That can also be said for C, assembly and almost any language, even Brainfuck.

And when there's not a speed/memory tradeoff for not having the language do the right thing (like e.g. is the case for some decisions in C), this just amounts to having the programmer do "busywork" -- manually do the work that the compiler/interpreter should have been doing instead.

Blaming the programmer for such errors is thus a kind of "blaming the victim".

The approach "The language X is totally fine, it's the programmer's problem who doesn't know what they're doing" for such cases, that is, cases where:

1) the right thing/warning could be inferred automatically

2) there's no (or not significant) speed/memory tradeoff to do so

is a bad idea and those that propagate it should feel bad.
