because I need to average of a list of numbers and it is not in this API

It kinda is. sum(@list)/@list.

That is not very DWIM. I take engineering software seriously. And aim for readability and conciseness. DWIM supports that greatly.	[reply]

How do you average numbers when you don't have a computer? I can't think of a more readable and DWIM-my way of writing something than by expressing the very definition of how it'd be done by hand.	[reply]

Kids learn the average is the sum divided by the count at a young age, so it's definitely readable. As for conciseness, `sum(@list)/@list` is really not that far off from `avg(@list)` Nothing is stopping you from putting that expression in a sub if you think it's not readable or concise enough.
