And what does exactly

131       my $func = $flags & qw/after/ ? 'signal_connect_after' : 'signal_connect';

line mean ?

Specifically, the '$flags & qw/after/' part ?

What is the meaning of '&' ?

Does 'qw' accept '/' as delimiter ? I have always used it as

qw(
  word1
  ...
  wordN
  )
.

Again, on '$flags & qw/after/' - '$flags' is scalar and 'qw/after/' is list,
so what was the intended operation ?

  Sergei.
