I see them most used as arguments/predicates to mapping functions or as
common-lisp predicates (eg. :test).

My complaint is against their use in situations that make standard
manipulation practices difficult: 1) When you assign a keybinding to a
lambda function, you can't remap to it; 2) When you add a lambda
function to a list, you lose the ability to perform operations such as
memq, delq, and you can't modify the element in place.
