in thread $^O empty in windows powershell

the following code does not output anything:

perl -e 'print "this is a test";'

I can't figure out why, shouldn't this work?

this works though:

perl -e 'print qq(this is a test);'

    my guess is that doublequotes are stripped from the input

    PS C:\Windows\system32> perl -E'say @ARGV' 'say "bla"'
say bla
PS C:\Windows\system32> perl -E'say @ARGV' 'say qq(bla)'
say qq(bla)
PS C:\Windows\system32> echo 'say "bla"'
say "bla"
PS C:\Windows\system32> echo 'print "bla"' |perl
bla
PS C:\Windows\system32> echo 'print "bla"' |perl -E'say <>'
print "bla"
PS C:\Windows\system32>

    this could be an artifact of Perl trying to repair input from CMD ... (?)

    (I think eyepops will soon come up with an older discussion about the Perl trying to cleverly fix CMD idiosyncrasies ;)
