- ($x) = ($^X =~ /^(.*)$/s); # $x is not tainted here
-
- use re "taint";
- ($x) = ($^X =~ /^(.*)$/s); # $x _is_ tainted here
-
- (We use $^X in these examples because it's tainted by default.)

- When use re 'taint' is in effect, and a tainted string is the target of a
- regex, the regex memories (or values returned by the m// operator in list
- context) are tainted.
-
- This feature is useful when regex operations on tainted data aren't meant
- to extract safe substrings, but to perform other transformations.
-
- See the section on _P_r_a_g_m_a_t_i_c _M_o_d_u_l_e_s in the _p_e_r_l_m_o_d_l_i_b manpage.
