10:07 PM Bug #17179 (Rejected): Unexpected warning during value assignment to setter

08:47 AM Revision 73a626c0 (git): [ruby/io-wait] update required_ruby_version
- As d387029f39d976565c955377117103499d47ff09 made io/wait
unbuildable with older versions, drop older versions tentatively.
Also the change seems to instroduce behavioral incompatibilities,

- And I'd argue if one wants to do everything in one block, just enjoy the freedom of imperative programming:
```ruby
result = []
array.each do |foo|
if bar = baz(foo)
result.concat bar.map{...}
end
end
``` -
- What's the problem with the obvious:
```ruby
array.map { |foo|
baz(foo)
}.select { |bar|
condition(bar)
}.flat_map { |bar|
bar.map{...}
}
```
I think it's so much more readable.
And I don't think the extra allocations ... -

- Unlike `[[1, 2], [3, 4]].each{|v| v.each{|v| p v}}`, nested numbered parametersin `[[1, 2], [3, 4]].each{_1.each{p _1}}` has no clue like `|v|` for nesting.
It is very hard to tell two `_1` have different meanings.
It is a possible c...
