Looking at 'perldoc -f open' this should work​:

perl -e 'open F, "-|", "ls", "-l"'

It does so on 5.8.0, but not on 5.6.0; it craps out saying​:

Can't use an undefined value as filehandle reference at -e line 1.

Only reporting this because I've heard that people are working on
5.6.2.

Thanks,

I doubt this is going to be fixed in 5.6.2, it is a 5.8.0 feature?

Its a 5.6.0 feature.

open FILEHANDLE,MODE,LIST

it appears that only works in 5.6.0 if LIST has one element. ie.

  open F, "-|", "ls -l"

The new "three arg open". It might be a bug or it might be ambiguous
documentation. Anyhow, its not going to get fixed in 5.6.2. 5.6.2 is
just fixes so it can work with recent compilers. 5.6.3 will address bugs...
whenever it comes out.

We don't know. But if we did, we wouldn't tell you.

But only a open-parsing one, not one that _needs_ PerlIO
so it could be back-fitted to 5.6 if someone had that much enthusiasm.
