The behavior of ECHO_ON_ASSIGNMENT being on by default is hard to understand,

10:07 AM Feature #17159: extend `define_method` for Ractor
- > #eval (...) has huge freedom to explode the program
I think this will happen too with the new feature proposed here.
One needs new bytecode/etc for the Proc/method where `i` is replaced by a literal value, isn't it?
Or do you alternat... -
- Copying captured variables seems a nice feature to have, also for optimizations.
In fact, this already exists in TruffleRuby internally:
https://github.com/oracle/truffleruby/blob/574d6bd2425caa856707ffd713fdb8ffc87be1e1/src/main/java/... -
- 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 ... -
