in reply to Re: Distinguishing a filehandle for an in-memory string
in thread Distinguishing a filehandle for an in-memory string

I noticed this, but I saw somewhere in a comment or in some piece of documentation that it says something like "currently returns -1", which made me think that that is not a reliable way to check. But maybe it's as reliable as checking for "scalar" in the list of IO layers?

    Checking for an in-memory handle is not what you want to check for. It's only one kind of Perl file handle that's not a system file handle.
