there;’s a lot of branches in repo that have been merged and not deleted

sure there is, I guess there is no automation removing those after merge/rebase.

would like to break thing a bit: mt/strip-extra-keys-transformer should be a function of options => Transformer , not a Transformer. Question: should it remove extra keys by default: a) from all maps (open or closed) b) only from closed maps

will add a option to control this, but leaning on a) as the default.

hm… how do I make a transformer that uses a schema property as param to transform function

you have this showcased in the :compile option example

but I’d like to look up something like that `

:math/multiplier

e.g. I have datetime schema and it’s transformer would like to check if schema had :format property

the :compile thing requires one to add it to every use-site

oh, I see how it’s done elsewhere, ignore that
