Internally, the match data that match variables represent are kept in Perl
variables, lists and hash tables, and are not interpreted. During the match
variable substitution, they are substituted as strings, and although this
does not allow to pass references, it does not alter string data.
Therefore, as long as you are working with strings, Perl function of the
lcall action should see your input data as is. Things are very different
with eval, where after match variable substitution the resulting code
snippet gets interpreted by Perl.
