Or, if you're like me and hate using the Perl debugger, you could 
insert a debugging line like this at strategic places in your code 
(such as just before/after each subroutine call using $t, just before 
the return $t statement, etc.):

print( "\$t == $t (". ref( $t ) . ") at line __WHATEVER__\n");

It sounds like somewhere or other you're losing your reference to the 
object, at which point $t no longer contains what you think it does.
