When the code is evalled, your lexical $string is not in scope, so all these tests are running against undef.

If I change the declaration to our $string, and refer to $::string within all the evals I get:

             Rate tr_loop eq_loop      tr      eq
tr_loop   96844/s      --    -26%    -96%    -98%
eq_loop  130666/s     35%      --    -95%    -97%
tr      2436420/s   2416%   1765%      --    -41%
eq      4137436/s   4172%   3066%     70%      --

which seems more reasonable.
