I just noticed the following (thanks to my persistent procrastination to
(of?) learn paredit, and some lucky unbalanced parenthesis): this issue
does not arise for `when', when it is bound as a variable inside a
`let', but it does for cond, nevertheless: the issue does also arise for
`when' as an argument of a defun.

I guess the reason of this oddity is macros and special forms are
treated differently, yet I can’t understand trivially why defuns args
and let args behaves differently as both are symbol to be bound…

But since `let' seems, at least for macros, to disable fontification,
“disabling fontification in some place” must not slow down that much
things I guess.
