What do you get from perl -MO=Deparse,-p script.pl for the offending chunk?

    I'll admit I haven't run the deparse before... so I can't read it very well (at least for this try catch stuff... But For the code that was added simply to prove that otherwise is defined.
    do { (my($k) = 2); 'sysAssert'->throw('test assert') }->try('err'->catch(do { (my($ex) = @_); print("caught by with\n"); dPrt('warn', " with $ex") }->with(do { (my($ex) = @_); print("caught by otherwise \n"); dPrt('warn', "OTHERWISE:$ex") }->otherwise)));
    For the original offending code that generates the error about can't call method "otherwise"... that I am trying to fix...
    if (($pbOnDStarMachine == 1)) { (my($sComm) = "sudo dchown nhmgenda '$$this{'sFullPath'}'"); do { libs::exec("$sComm") }->try('err'->catch(do { (my($ex) = @_); dPrt('warn', "$ex") }->with(do { (my($ex) = @_); dPrt('warn', "OTHERWISE:$ex") }->otherwise))); return(''); }

      No surprise. It just confirms that Perl thinks you have indirect method calls where you didn't mean use such. In both cases.

      Could you place the following just before your sub and provide the output:

      BEGIN { no strict 'refs'; no warnings 'uninitialized'; printf("package %s\n", __PACKAGE__); for (qw( try catch with otherwise err )) { printf("%s: exists:%s defined:%s prototype:%s\n", $_, exists(&{$_}) || 0, defined(&{$_}) || 0, prototype($_), ); } }

      Update: Removed bad slashes.

        Well it seems I have stumbled onto a fix...
        Previously the Error.pm was pulled in by one of my modules (myExceptions), which was pulled in by another module, that was pulled into the one running the code. Apparently that we too many levels or something, somehow (since it works in some cases not in others). But when I directly pulled in myExceptions in the module doing the code, it started working.
        All said and done, this is better coding this way anyway...
        So thanks for all the help... the otherwise clause does indeed work the way we thought... and all is well (well the script still doesn't work, but this isn't the reason why... :) )
