(with-no-warnings (byte-compile '(:foo)))
produces the warning
Warning: ‘:foo’ called as a function
Setting byte-compile-warnings to nil also does not suppress this
warning. So either the documentation or the operation of both
with-no-warnings and byte-compile-warnings is incorrect.
In fact, it seems a little inconsistent to me that none of
(defun :foo ())
(byte-compile ':foo)
(:foo)
produces any warning, but compiling the call of :foo does produce a
warning.

I think it should rather be like this (shows the same warning):
(byte-compile (lambda () (with-no-warnings (:foo))))
> produces the warning

Seems to have been the case at least as far back as 24.3, and probably
farther.

I think the warning is just missing a `byte-compile-warning-enabled-p'

Maybe (byte-compile (lambda () (defun :foo ()))) should give a warning,
though I don't see why the others should.
