@ -1532,8 +1532,20 @@ For extra information read [Peter Seibel's thorough discussion about
* Add metadata support to composite data types, symbols and native
functions. TODO
* `time-ms` TODO
* `conj` TODO
* Add the following new core functions:
* `time-ms`: takes no arguments and returns the number of
milliseconds since epoch (00:00:00 UTC Janurary 1, 1970), or, if
not possible, since another point in time (`time-ms` is usually
used relatively to measure time durations). After `time-ms` is
implemented, you can run the mal implementation performance
benchmarks by running `make perf^quux`.
* `conj`: takes a collection and one or more elements as arguments
and returns a new collection which includes the original
collection and the new elements. If the collection is a list, a
new list is returned with the elements inserted at the start of
the given list in opposite order; if the collection is a vector, a
new vector is returned with the elements added to the end of the
given vector.
