Nice example, :) but no, my task can't be converted to something like this. Here is complete story. I've template like: "some text @~var1~@ some other text @~var 2~@ end of text" and I've this hash: { "var1" => $value1, "var 2" => $value2, }. So: 
$tmpl =~ s/@~(.*?)~@/$hash{$1}/g;

But I wish to add some protection here. Minimum: 
$tmpl =~ s/@~(.*?)~@/
    defined $hash{$1} ? $hash{$1}
  :                     croak("@~$1~@ not defined")
  /ge;

[download]
Maximum - also detect orphaned @~ and ~@ like in this example: "some ~@ text @~ here @~".
