Re^2: Can't clone STD handle with :via layer

As i correctly understand '>&' - is standard technique to clone handle.

I use Capture::Tiny, which clone all STD handles on each call. Probably other CPAN code may use handle cloning too. So i wish to understand, why cloning with :via layer not working.

Maybe something missing in PerlIO::via::QuotedPrint - which prevents cloning normally?

It's nothing specific to PerlIO::via::QuotedPrint; it seems to happen with all PerlIO::via::* modules, but not with built-in layers like `:unix`, `:utf8`, or `:encoding(iso-8859-1)`. Update: indeed, the error message is generated within PerlIO::via. Here's the relevant code. `use Moops; class Cow :rw { has name => (default => 'Ermintrude') }; say Cow->new->name`	[reply] [d/l] [select]

Maybe it makes a sense to create issue in perl rt?	[reply]
