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=E2=80=99t understand trivially why defuns ar= gs and let args behaves differently as both are symbol to be bound=E2=80=A6 But since `let' seems, at least for macros, to disable fontification, =E2=80=9Cdisabling fontification in some place=E2=80=9D must not slow down = that much things I guess.
