I'm a practical man, for me it's just n_loc difference and more useful imlicitness (and the listed downsides). Not sure if I can understand this "creation" part, even as a former Perl-ist. I think you can turn any language into Perl, it just happens that their core beliefs are incompatible with its ways.

For example, I can easily imagine something like this:

  import 'use-perl'

  while (await ls_lr('./*.txt')) {
    while (await read_lines($filename)) {
      print($ln, $line)

But it's not idiomatic as it uses awful implicit iterators and hideous globals. This conflict is purely dogmatic and doesn't need special syntax, for the most part.
