An identity generator that uses ever increasing numbers.

Use in place of UUIDs when testing.

Deeply merge maps.

Fetch the content of a URI and present it with the same structure as stored
content.

Map only the values in a map to produce a new map.

Open a `Keystore`.

Recursively transform every primitive value in map `m` by passing it to `f`,
while retaining the structure of `m`. Sequential values are transformed in
parallel.

Like swap-vals! in Clojure 1.9.

Time the specified expression and return a vector containing execution time
(in milliseconds) and the expression result.

Recursively transform every primitive value in map `m` by passing it to `f`,
while retaining the structure of `m`.

Produce factory functions that construct UUIDs represented as strings.

Close `closeable` when the items being waited on have all been done.

Returns a function taking one argument, the item from the `waiting` set, that
has completed.
