Hi Alex,
I pushed a commit to master for ?change-at with two slight changes.
1) I kept the ( key assoc quot -- ) stack effect that ?change-at has.
2) I used ``at*`` so that it works with keys that have a value of ``f``.
Your version uses ``of`` which is like ``at`` and doesn't distinguish
Ah, gotcha!
That could be cool. I’ll push a commit later for that!

I think Alex wanted the conditional execution of the quot.
if the key doesn't exist in the assoc, change-at provides f as value,
but still stores the newvalue in the assoc at the given key.

Hello!
I came up with this code, because I could not quickly find an existing word
for this.
Did I miss it? If not, would it be a useful addition to the assocs vocab?
! If key exists in the assoc, change its value with quot.
: ?change-value ( assoc key quot: ( value -- value' ) -- assoc' )
