I wish there was a Map.filter_values function that would filter on keys or
values, but leave the other one intact. This seems like something that
should be in the standard library.
Example implementation of a Map.filter_values that would filter a map based
on its values, leaving the keys intact
ere's
already Map.take/2 which is somewhat similar in functionality to
filter_keys.

Could this be done automatically by the compiler? Replacing `String.length
str >= 13` with `String.at(str, 13) != nil`?

Right could be confused with correct. If the changes happens, make sure the
lines still line up, i.e. add an extra space after "left".

Why aren't lists and tuples implementing `Access`?
{:a, :b, :c}[1] == :b

Would it hurt to add it?

I'd like ExUnit to sort its output by source code line number and path.
This simplifies fixing multiple test cases in a row, when that's what
you're doing, and it shouldn't slow down other development. If it would
noticeably slow down parallell testing, only sorting output when
`--max-cases 1`
x27;t sort the failure output.

I often find myself writing
def func(a,b):
g = :digraph.new
...
out = some_long_multiline_expression_using_g
:digraph.delete g
out
end
when working with graphs. The distance between `:digraph.new` and
`:digraph.delete` makes it harder to remember to clean up the graph ets
tables. T
I love the flow of how pipelines read top-down as a series of steps, but
there's something I don't like about it; having to look back at the start
of the pipeline again to see in what variable the result is stored. It's an
uncanny valley; reading functional code top-down is really clear and easy
