in thread using eval or equivalent to automatically generate my statements

Thank you for all yor help. Unofortunaely, I was granted very short time to do a rather thankless task. Theoretically, scratching it and start anew is the way to go. I have no management green light to do so, and the decision is not without reason. It took > 5 years of on-going user feedback to get where we wanted.

I was hoping to see some really cool PERL magic, it may be for the best, but it would have been one cool metaprogramming feat...

    OK, so as not to disappoint...

    Introducing Acme::Asplode: it lets you drag your caller's lexical variables kicking and screaming into your sub. Ought to work in Perl 5.12+.

    Example usage...

    use 5.012; use strict; use warnings; use Acme::Asplode; sub bar { asplode($x, $y); # steal lexical variables from our caller! say $x; say $y; asplode @A, $z; # steal moar lexicals!!! say $z; $z++; # alter our caller's lexical variable!! say for @A; }; sub foo { my $x = 1; my $y = 2; my $z = 3; my @A = qw(a b c); bar(); say "Z is changed: $z"; } foo();

    Update: Acme::Asplode, renamed Acme::Lexical::Thief is now on CPAN.

    perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'
