Re^2: keys %::

Yes... to see if something is a scalar you can do *something{SCALAR}. if it is a scalar then it will exists and it will be defined... (read `perldoc perlmod` if you need more information)

Or you could use the Devel::Symdump package...

I seem to recall that every glob has an SV in the scalar slot as an optimization, but I can't confirm it by reading the source code. (I'm not sure I've even found the right spot in the code.)	[reply]

Indeed it is so, for when I first tried I noticed that the 'SCALAR' key always seemed to be there, which surprised me and back then I checked into the docs to discover that it was supposed to be so. I think it hasn't changed since...	[reply]
