This isn't perl.  It's stty.  Do an stty -a, and see that "status" is set to.
For example:

% stty -a
...
cchars: discard = ^O; dsusp = ^Y; eof = ^D; eol = <undef>;
        eol2 = <undef>; erase = ^H; intr = ^C; kill = ^U; lnext = ^V;
        min = 1; quit = ^\; reprint = ^R; start = ^Q; status = ^T;
        stop = ^S; susp = ^Z; time = 0; werase = ^W;

Note I have it set to ^T.  So if i run 
% perl
and hit ^T, I get:
load: 0.06  cmd: perl5.00502 21939 [ttyin] 0.00u 0.00s 0% 860k

but of course I could also run cat
% cat
load: 0.07  cmd: cat 21938 [ttyin] 0.00u 0.00s 0% 88k

You must have status bound to whatever backspace is.  To see what backspace
is sending for you, type ^V then backspace (^V means control-V of course).
