Issue #16791 has been updated by Dan0042 (Daniel DeLorme).


Those short aliases are definitely a bad idea but I understand the OP's frustration with `$?` because it's different from the shell's `$?`. Process::Status has several methods that I'm sure can be useful in various circumstances, but the only one I've ever needed was `exitstatus`. It's a bit irritating when you have to write the verbose `$?.exitstatus` (get the exit status of the exit status?) instead of the shorter and more natural `$?`, especially for the common case of `exit $?`

```
s = `csc x.cs`.sub(/.*?\n\n/m, '')
puts s if s != '';   exit $?.exitstatus if $?.exitstatus > 0
system 'mono x.exe'; exit $?.exitstatus
```
```
class Process::Status
    alias :es :exitstatus
end
```
```
s = `csc x.cs`.sub(/.*?\n\n/m, '')
puts s if s != '';   exit $?.es if $?.es > 0
system 'mono x.exe'; exit $?.es
```
