What are you trying to report? Are you trying to emit something for every executed function? In that case, close over the name of the wrapped function:

my @mars_subs = qw( add increment ); for my $sub (@mars_subs) { wrap $sub, pre => sub { print "Calling '$sub'\n"; }; }

    Thanks. Yes, I want to log how these various subroutines are called one after the other, for understanding how this set of perl scripts and modules works and the dependencies between them. It's all legacy code of thousands of lines. Is there a better way to do this?
