Sometimes text in comments in ClojureDocs.org examples can be more useful
than the examples. They are effectively longer (unofficial) doc strings.

Go for it. Not sure the type stuff is adding anything in the context of
quote examples here beyond the other explanation though.

Aah! "without evaluation" is the key! Now it makes sense. Yea you
mentioned it before already, but it takes twice the effort to undo and
re-comprehend an acquired misconception. Thank you so much!

I think it's not the special case of nil, false and true what's
causing me headache. I'm ha
You can see the special cases of nil, false, and true in the LispReader

Why is then (boolean (quote nil)) => false and (boolean (quote

Sets are treated as predicate functions which are valid when they produce a
logically true value. Sets with logically false values nil or false will
fail this check. This is not a spec thing, but a general thing to be aware
of in Clojure when using sets as functions.
If you want nils, use (s/ge
Could anybody explain please why I can't get a sample of falses or
