Good Point!

What do you mean "no such anymore"? $^T == $^t == $<ctrl-T> is time.
I don't know how long it's been there, and whether or not it
once was, then wasn't. But with $^t it certainly is now! I wonder
if we can expect $^h to be our hostname, etc. On a PDP-11, I
would guess that $^f would be the switch register :-)
