I don't like this syntax very much. It looks too much like dumping the
output of a command ("transcript") to the file, not like a redirection
for the future output. If I were in hard-core shell mode this week I'd
suggest "exec > FILE" but I don't really like that one much either...
Also - is piping to a command actually useful?

Hmm... How do you feel about:
transcript [-append] FILE
tee [-append] FILE
Where transcript replaces ">" and ">>"?
