Because it's not a bug.

1)  You're using a FileHandle.

From the FileHandle manpage:

>       NOTE: This class is now a front-end to the IO::* classes.

From the IO::Handle manpage:

>       The following methods are not supported on a per-filehandle basis.
>           IO::Handle->input_record_separator( [STR] )       $/

The manual is fine.  Please read it.

Mx.
