in thread variable scopes in Excel::Writer::XLSX
If you look at this code...
By "this code", I assume you mean the code posted at the end of the Re^2: variable scopes in Excel::Writer::XLSX node, and that this code is all that is needed to produce the error you describe. (I'm not in a position right now to run the code; all I can do is literally 'look' at it.)
... I see no reason that the one extra assignment should cause an error.
Nor do I. The $closure_workbook variable is never touched except to assign it a value in certain circumstances. It is never otherwise accessed within func() and no other function than func() can possibly access this lexical variable (unless there's something you're not showing us). The next step is to eliminate the
if (@_) {
$closure_workbook = $book;
}
block of code (leaving the my $closure_workbook; statement just for grins) and see if the error still occurs. My bet is it will. This means the root cause of your problem is entirely unconnected to anything you're doing with this 'closure' variable.
For a while, I had my suspicions about the &func(@ARGV); ampersand invocation of func(), but I can't see this has any relevance.
Update: Oops... Should have refreshed the thread before posting. I see from Re^4: variable scopes in Excel::Writer::XLSX that the problem is resolved. At any rate, the problem had, indeed, nothing to do with anything that was happening with the 'closure' variable.
