I strongly agree. Map / filter isn't included, but a fair number of the various utilities are included in the standard library in the `slices` and `maps` packages.

`context` also helps solve a bunch of the channel related use cases in a more elegant (IMO) way.

There are only a handful of things in that package I wish were included, such as "Keys()" on a map.

FYI - “Keys()”, “Values()” and others have been pulled because they’re likely to be implemented using the new range-over-function paradigm.

They were included in the experimental packages on google.com/x.
