Using scalars for file handles without relying on auto-vivication: gotcha.

What does $self->{handle} have to do with my $handle ?

    Sorry for being unclear. My warning is that when you start using any old scalars as filehandles, people are likely to expect that you can use any construct that gives a scalar as a filehandle. Unfortunately this doesn't work.

    And a classic case that causes confusion comes when you put the handle in an object and then wonder why the obvious syntax doesn't work very well...

      Yea, I've hit that myself (not for files, though) where I forget that I'm implicitly omitting braces, and that only works on a simple scalar name.
