No one has mentioned (I think) that filehandles are actually 'typeglobs'
yet so I thought I'd chime in on this. They also actually do have an
associated sigil: '*'.
There's plenty of explanation on filehandles in typeglobs in the
following documents:
perldoc perldata (Heading: 'Typeglobs and Filehandles')
The 'SEE ALSO' section of the data document points to more information
on typeglobs:
See perlvar for a description of Perl's built-in variables and a
discussion of legal variable names. See perlref, perlsub, and
"Symbol
Tables" in perlmod for more discussion on typeglobs and the
*foo{THING}
syntax.
