Re: file handle var for print command

See print:

If you're storing handles in an array or hash, or in general whenever you're using any expression more complex than a bareword handle or a plain, unsubscripted scalar variable to retrieve it, you will have to use a block returning the filehandle value instead, in which case the LIST may not be omitted:

So, if you're storing the filehandle in a complex structure, you need the block:

print { $self->{fh} } encode( ... )

This also works as expected, but I couldn't find a documented explanation for it: `$self->{fh}->print("test with print\n");` [download]	[reply] [d/l]

Filehandle GLOBs behave like `IO::Handle` instances (but aren't actually for purposes of inheritance according to the BUGS entry in the IO::Handle docs) so that's just a normal method call to the `print` method and doesn't get into weird indirect object parsing corners. The cake is a lie. The cake is a lie. The cake is a lie.	[reply] [d/l] [select]

Not quite. They behave like IO::File objects (since 5.12). `$ perl -e'STDOUT->foo' Can't locate object method "foo" via package "IO::File" at -e line 1.` [download] They do obey inheritance. `$ perl -e'use IO::File; IO::File::say( STDOUT, "ok" )' Undefined subroutine &IO::File::say called at -e line 1. $ perl -e'use IO::File; IO::Handle::say( STDOUT, "ok" )' ok $ perl -e'STDOUT->say( "ok" )' ok` [download] (IO::Handle's docs is merely saying IO::File isn't a derivable class since `My::IO::File->new` will create an IO::File "object" instead of a My::IO::File object.) And the issue raised wasn't why it works; it was about where it's documented. I could not find it either.	[reply] [d/l] [select]
