Slightly related: auth-source.el uses `lexical-let' to define lambda
accessors for secrets (so printing them, for instance, won't show a
password). Will the secrets still be hidden in the lexbind branch? And
is there a smarter way to do it?
Sample code:
(let ((data "my secret"))
(lexical-let ((data data)) (lambda () data)))
Thanks
Ted
