walkmap.tag
Code for tagging, untagging, and finding tags on objects. Note the use of the namespaced keyword, :walkmap.tag/tags, denoted in this file ::tags. This is in an attempt to avoid name clashes with other uses of this key.

(tag object & tags)Return an object like this object but with these tags added to its tags, if they are not already present. It is an error (and an exception will be thrown) if
objectis not a map;- any of

It’s legal to include sequences of keywords in tags, so that users can do useful things like (tag obj (map keyword some-strings)).

objectis not a map;- any of
