In the Perl Reference Guide there is a reverence to
$^T ($ control-T), which is:
The time (as delivered by "time") when the program started.
This values is used by the file test operatores "-M", "-A" and
"-C".
This variable is NOT mentioned in the perl man page.

Guess again. Either way works. If you go back to Perl version 1, you'll
see the hooks for using control characters as special variables.
Of course, anyone in their right mind will use the caret notation.

That part is right. Though I usually try to document features as they're
added.

Existing perl programs that will break deserve to do so.
