Replying to [comment:2 ehird]:
> I don't like `$++`; it should be a textual keyword, like `do`.
There have been a couple of good suggestions in those reddit comments. My
favorites so far:
* `cat` or `mcat` (if we use monoids instead of plain lists)
* `be` (as in not `do`-ing anything)
On IRC there has also been mentioned that further layouts could be thought
of, e.g. an "application" layout which simply applies all its elements to
the previous function:
{{{
foo $$
bar a b
baz x y
=>
foo (bar a b) (baz x y)
}}}
Or a record layout:
{{{
MyRecord {{
a = 0
b = c
=>
MyRecord { a = 0, b = c }
}}}
If you're willing to accept these (and maybe more in the future) layouts
I'd guess the extension should be named "ExtendedLayouts" or something
similar.
