Hi ,

Thanx for your insight - looks like UNITCHECK or, probably, CHECK would be the way to go.

Way to go kyle :-))

Update

Thinking about it, using the CHECK block would be best as it's also run when using perl -c .... Something like the following would possibly suffice (based on code supplied elsewhere in the thread 702588)...

CHECK {
  my $dp = B::Deparse->new();
  while (my ($pkg, $hash) = each %INTERFACES) {
    while (my ($var, $glob) = each %{"${pkg}::"}) {
      next unless defined &$glob;
      croak "Constructor detected: ${pkg}::$var" if
        $dp->coderef2text(\&{"${pkg}::$var"}) =~ /\bbless\b/;
    }
  }
}

Note that this is not too much more than thinking aloud i.e. code untried and untested ... yet;-)

Further Update

Corrected typo (missing trailing slash) in RE
