You could use sub references instead:

@listofsubs = (\&sub1, \&sub2, \&sub3);
foreach $sub (@listofsubs)
{
  $sub->();
}

Or you might be doing this on objects:

foreach $sub (@listofsubs) {
  $self->$sub()
}
[download]

Or you could just try to find them... if they're in the current package, this might work (untested):

foreach $sub (@listofsubs) {
  if (not ref $sub)
  {
    $sub = __PACKAGE__->can($sub);
  }
  $sub->();
}
[download]

(by checking if it's a ref, you could comingle names and code-refs: @listofsubs = ('sub1', \&sub2, sub { do_stuff() }); - the object example can handle this, too, only better.)
