Hi all, I'm moving towards Emacs as an old vim user, with the goal of giving up my heathen C ways in favor of Lisp.

Attempting to use slime on a fresh install gives the error: Eager macro-expansion failure: (wrong-number-of-arguments (3 . 4) 2)

wth is this? ):

you need to update all your packages first before loading any user inti file to isolate other issues.

the root cause of the error is that define-obsolete-variable-alias now requires four arguments instead of three (and one optional argument). so outdated packages may use wrong calling conventions.
