Hi All,
I have been using "flatten" for a while. I kinda-sotra know
what it means.
From the following,
https://docs.perl6.org/routine/[%20]#language_documentation_Operators
The Array constructor returns an itemized Array that does not
flatten in list context.
What exactly do they mean by "flatten" and "list context"?
Many thanks,

Whoever just wrote me on "flatten", would they please
resend. My iMap server is on the fritz again.
It just showed up:

Hopefully you see emails in a fixed width font and the As are in a vertical
line.
If not, imagine they were, so there's a T shape.
Imagine the horizontal line of four Es, then 3 As vertically, then four more
Es, is a list.
In this scenario, the horizontal line is a list of 9 elements.
The vertical line is an array (which is an "itemized" list) that
has not flattened into the outer list .
If it had flattened, you'd have instead ended up with 11 elements:
EEEEAAAEEEE
Make sense?
