Which is quite reasonable, e.g. echo more >>file

By the way, for completeness, I should maybe point out that something
like this existed also for Linux. It was called "IFS" (Inheriting File
System), and was an ugly in-kernel hack that was far too complex and
was never fully debugged. In fact, it was so bad that even its author
admits that it was the wrong approach:
