> I've always had trouble getting `for` loops to work predictably, so my common loop pattern is this:

for loops were exactly the pain point that lead me to write my own shell > 6 years ago.

I can now iterate through structured data (be it JSON, YAML, CSV, `ps` output, log file entries, or whatever) and each item is pulled intelligently rather than having to conciously consider a tonne of dumb edge cases like "what if my file names have spaces in them"

eg

    » open https://api.github.com/repos/lmorg/murex/issues -> foreach issue { out "$issue[number]: $issue[title]" }
    380: Fail if variable is missing
    379: Backslashes and code comments
    378: Improve testing facility documentation
    377: v2.4 release
    361: Deprecate `swivel-table` and `swivel-datatype`
    360: `sort` converts everything to a string
    340: `append` and `prepend` should `ReadArrayWithType`

Powershell is also a good option nowadays (although a lot of people on HN seem to dismiss it for various, imo rather superficial, reasons).

  PS> (irm https://api.github.com/repos/lmorg/murex/issues) | % { echo "$($_.number): $($_.title)" }
  380: Fail if variable is missing
  379: Backslashes and code comments
  378: Improve testing facility documentation
  377: v2.4 release
  361: Deprecate `swivel-table` and `swivel-datatype`
  360: `sort` converts everything to a string
  340: `append` and `prepend` should `ReadArrayWithType`

Or just

  PS> (irm https://api.github.com/repos/lmorg/murex/issues) | format-table number, title

  number title
  ------ -----
     380 Fail if variable is missing
     379 Backslashes and code comments
     378 Improve testing facility documentation
     377 v2.4 release
     361 Deprecate `swivel-table` and `swivel-datatype`
     360 `sort` converts everything to a string
     340 `append` and `prepend` should `ReadArrayWithType`

Or even `(irm https://api.github.com/repos/lmorg/murex/issues) | select number, title | out-gridview`, which would open a GUI list (with sorting and filtering), but I think that only works on Windows.

The reason I dismissed Powershell was that it doesn't always play nicely with existing POSIX tools, which is very much not a superficial reason :)

Murex aims to give Powershell-style types but still working seamlessly with existing CLI tools. An attempt at the best of both worlds. But I'll let others be the judge of that.

It's also worth noting that Powershell wasn't available for Linux when I first built murex so it wasn't an option even if I wanted it to be.
