Er, no.
To quote the Camel book on open(): "FILEHANDLE may be a directly
specified filehandle name, or an expression whose value will be used
for the filehandle. The latter is called an indirect filehandle.
Typically it is just a variable containing the name of a filehandle."
So there are contexts in which you might want to use a scalar as
a filehandle.
